## Plot

In 1992, shortly after the end of his first year at Hogwarts School of Witchcraft and Wizardry during the first film, Harry Potter (Daniel Radcliffe) spends a dreadful summer at the Dursleys' house without being allowed to use magic outside of school nor receiving any letters from his new friends, Ron Weasley (Rupert Grint), Felicity Black (Kayleigh Davidson), and Hermione Granger (Emma Watson), all of whom he is unable to contact because neither his Aunt Petunia (Fiona Shaw) nor Uncle Vernon (Richard Griffiths) would allow their nephew's pet owl Hedwig out of her padlocked cage. On the evening of his twelfth birhday, he is visited in his room and warned that he will be in mortal danger if he returns to Hogwarts by a House-Elf named Dobby (Toby Jones), who reveals that he has intercepted all of the letters to make it seem as though Harry's friends had forgotten him, hoping that it will then dissuade Harry from returning. But Harry ignores the warning and is determined to seize the letters, so Dobby, seeing that he will have to use force, heads downstairs and destroys a large cake that Petunia has baked for an important dinner party which Vernon is holding downstairs for the family of his client Mr Mason (Jim Norton) by the use of a Hover Charm, dropping it on Mrs Mason's (Veronica Clifford) head. Robbed of this one chance that could've been the turning point of his career as a director of the drill company Grunnings, Vernon imprisons Harry by fitting bars onto his bedroom window to restrict him from returning to Hogwarts for his second year as punishment.

The next night, Ron and his older brothers Fred and George (James and Oliver Phelps), come to Harry's rescue in an enchanted Ford Anglia belonging to their father, Head of the Ministry of Magic's Misuse of Muggle Artefacts Office, Arthur Weasley (Mark Williams). After a pleasant stay together in the Weasley home, The Burrow, Harry accompanies the family on a trip through the Floo Network to buy some first year school supplies for Ron's younger sister, Ginny (Bonnie Wright), in Diagon Alley, where they encounter Flick, Hermione and Rubeus Hagrid (Robbie Coltrane) while attending a book signing at Flourish and Blotts for flamboyant celebrity author Gilderoy Lockhart (Kenneth Branagh), who is recently appointed to teach at Hogwarts as the new Defence Against the Dark Arts professor. After the signing, the quartet run into their school rival Draco Malfoy (Tom Felton) and his father, Lucius Malfoy (Jason Isaacs), who manages to slip a diary into Ginny's belongings while arguing with Mr Weasley about the latter's recent Muggle Protection Act for the Ministry.

The quartet and Weasley children head to Platform Nine and Three-Quarters at King's Cross to take the Hogwarts Express back to school, but Dobby seals the barrier between platforms nine and ten on Harry and Ron and makes them miss the train. As a loophole, however, the two boys instead fly to Hogwarts in the Ford Anglia, which unfortunately runs out of fuel for its Invisibility Booster when it catches up to the train (allowing the "flying car" to be seen by numerous Muggles) and crashes into the Whomping Willow on the school grounds. Ron's wand is damaged and the semi-sentient car ejects them with their belongings before disappearing into the Forbidden Forest. School caretaker Argus Filch (David Bradley) brings them to Potions Professor Severus Snape (Alan Rickman), who shows them the sightings of the car in the *Evening Prophet* and threatens to have them expelled. However, Headmaster Albus Dumbledore (Richard Harris) and Deputy Headmistress, Transfiguration Professor Minerva McGonagall (Maggie Smith) intervene by deciding that they will instead be sanctioned with detention.

Harry soon finds he is the unwanted centre of attention of three people due to being famous: Lockhart, who wants to boost Harry's fame, Colin Creevey (Hugh Mitchell), who takes a picture with Harry, and Ginny, who has a huge crush on Harry. However, while serving detention with Lockhart on Halloween, events take a turn for the worse when Harry hears strange voices and later finds the petrified body of Filch's cat, Mrs Norris, hanging on a torch clamp. On the wall near it is a message written in blood announcing that the "Chamber of Secrets has been opened" and that enemies of the heir should take extreme caution. Unknown to everyone, a monster/monstrous creature stalks the castle, with the power to literally petrify several students. During a Transfiguration class, McGonagall explains that according to legend, one of the school's founders, Salazar Slytherin, built a secret Chamber and sheltered a monster in it before leaving the school for good. Only his heir can open the chamber and use the monster to purge impure-blooded wizards and witches whom Salazar deemed unworthy to study magic.

More attacks occur over the course of the year. The quartet suspect Malfoy is the heir, so Hermione suggests they question him while disguised using Polyjuice Potion. Their makeshift laboratory is in a disused bathroom haunted by the spirit of a former Hogwarts student named Myrtle Warren (Shirley Henderson), whom the school community addresses as "Moaning Myrtle."

During duelling club, hosted by Snape and Lockhart, Malfoy conjures a cobra which menaces at a Hufflepuff student named Justin Finch-Fletchley (Edward Randell). Harry manages to control the snake by inadvertently revealing his ability to speak a serpent language known as Parseltongue before Snape vanishes the carnivorous reptile. This causes the school to suspect that Harry is the Heir of Slytherin. Unknowingly, Harry managed to gain the rare ability on the night Voldemort failed to kill him when the former was still an infant.

On Christmas, the quartet uses Polyjuice Potion brewed by Hermione to disguise themselves as Slytherin students, Vincent Crabbe (Jamie Waylett), Gregory Goyle (Josh Herman), Pansy Parkinson (Katherine Nicholson) and Millicent Bulstrode (Helen Stuart), hoping to learn from Malfoy the identity of the Heir. Unfortunately, the hair that Hermione took from Millicent Bulstrode's uniform was from a cat, and as the Polyjuice Potion is only intended for human transformations, she assumes a feline appearance, leaving Harry, Ron and Flick to ask for information by themselves. In the Slytherin Common Room, they learn that Malfoy does not know who the Heir of Slytherin is, but he inadvertently provides them with an important clue about the Chamber of Secrets that his father had told him; a girl died when the Chamber was last opened fifty years ago. As the potion begins to wear off, the trio discover Hermione's feline appearance and that it would take a little more than a month to restore her to normal human form.

Before Hermione is released from the hospital wing in early February with her normal appearance restored, Harry finds an enchanted diary, owned by a former student named Tom Marvolo Riddle, which shows him a flashback t the year 1943, exactly fifty years before. In the flashback, Harry witnesses four wizard authorities carry away Myrtle Warren's corpse from Hogwarts and Riddle, trying to find the problem, accused Hagrid, then a student, of opening the Chamber and freeing the alleged resident monster, a giant spider named Aragog. Riddle's actions caused Hagrid's expulsion later on.

The attacks increase throughout the year, petrifying more students, including Hermione. Whe the diary disappears and Harry, Ron and Flick are shown Hermione's body, the trio go to Hagrid to question him. But before they can do so, Professor Dumbledore, Cornelius Fudge (Robert Hardy), and Lucius Malfoy come to take Hagrid to Azkaban, but he discreetly tells the trio to "Follow the spiders" and take care of his pet dog, Fang. Lucius then has Dumbledore suspended. In the Forbidden Forest, Harry, Ron and Flick, accompanied by Fang, meet Aragog, a giant spider who reveals Hagrid's innocence and informs them of the discovery of a girl's corpse in a bathroom before giving a clue of the resident monster which he and his species fear and never speak of. Aragog them sets his colony of Acromantulas on them, but the now-wild Ford Anglia saves the three.

A torn book page in Hermione's hand identifies the resident monster as a Basilisk, a giant serpent that instantly kills those who make direct eye contact with it and only petrifies those who see it indirectly. Piecing the evidence together, Harry, Ron, and Flick find out about the casue of petrification of Colin, Justin, Nearly-Headless Nick, Hermione, and Mrs Norris: Colin had his camera, Justin saw it through Nick (who absorbed the full force of the basilisk's stare, but could not die again as he was already dead), Hermione saw it through a mirror, and Mrs Norris saw it through a reflection in a puddle of water. The trio also discover that the basilisk used the school's plumbing and from Aragog's statements the previous night, they realise that Moaning Myrtle was the girl found in the bathroom.

The teachers discover a new message written on a wall declaring that Ginny Weasley has been taken into the Chamber, where "her skeleton will lie forever," and convince Lockhart to save her. Harry, Ron, and Flick find Lockhart, exposed as a fraud who wipes clean other wizards' memories and claims their achievements, planning to flee. Knowing Myrtle was the girl the Basilisk killed, they drag him to her bathroom where they discover the Chamber's entrance behind a circular column of sinks, a pipe big enough for a man to crawl through.

The four jump through the hole and land in a series of cavernous maze-like crypts and dungeons. Following the tunnels, they find a shed basilisk skin wherein Lockhart feigns a collapse to seize Ron's broken wand and use to to erase the trio's memories. But as Lockhart casts Obliviate it backfires on himself, wiping his memory. The force of the spell also causes a portion of the ceiling to cave-in, separating Harry from Ron, Flick, and Lockhart.

Harry ventures further to the tunnels and finds a circular door which is the entrance to the Chamber itself. He enters the Chamber where he finds an unconscious Ginny. As Harry tries to examine the body, he is greeted by the ghostly memory of sixteen-year-old Tom Riddle. After Riddle reveals to Harry that he is the memory preserved in the diary, he adds that he manipulated Ginny to open the Chamber and write the bloody messages on the walls, and how the diary traumatised her in February wherein she tried to dispose of it.

Riddle then reveals his full name, Tom Marvolo Riddle, and the anagram he fashions out of it which reveals "I am Lord Voldemort". At this point Harry learns that Voldemort's real name was that of Riddle himself and was the true heir of Slytherin. Riddle reveals more on how he imprinted his 16-year old self as memory in an enchanted diary, in order to one day continue the failed work of his ancestor which he began when he opened the Chamber fifty years ago, ridding Hogwarts of impure-blooded witches and wizards. He also adds on how he framed Hagrid for the attacks and how he would make his new pseudonym a feared name in the wizarding community and how he would replace Dumbledore as the greatest sorcerer. After Harry expresses support for both Dumbledore and Hagrid, Dumbledore's phoenix, Fawkes, flies in with the Sorting Hat.

In an attempt to kill Harry, he unleashes the basilisk from the statue of Salazar Slytherin himself, but Fawkes, arrives and blinds the basilisk, destroying its fatal gaze. After a short chase and Harry's diversion, Harry returns to re-examine Ginny. Tom Riddle's memory grows more powerful as it steals life from Ginny's body.

The basilisk emerges from the pool of the chamber and while Harry tries to find other means of fighting, the sword of Godric Gryffindor materialises from the Sorting Hat. Climbing the statue of Salazar Slytherin, he duels with the basilisk and manages to kill the monstrous creature by impaling the roof of its mouth with the sword. However, one of the creature's fangs pierces Harry's sword arm as a result of the latter's killing move. Harry manages to remove the fang as he and Riddle watch the basilisk slam dead to the chamber's floor. As Harry is slowly being poisoned, he uses his remaining energy to stab the diary with the the basilisk's fang, and the memory of Tom Riddle is destroyed, while Ginny revives from her near-death state. As Harry advises Ginny to get out of the Chamber with Ron and Flick, Fawkes comes to heal Harry with his tears, which have healing powers. Ginny and Harry both recover fully, along with those who were petrified: Hermione, Mrs Norris, Justin Finch-Fletchley, Nearly Headless Nick (John Cleese), and Colin Creevey.

The next morning, Harry realises it was Lucius Malfoy (Jason Isaacs), Draco Malfoy's father, who slipped the diary into Ginny's cauldron when he encountered the Weasleys in a Diagon Alley bookshop, but he is unable to prove it. Dobby reveals he is the Malfoys' servant, and knowing their treachery, had been trying to protect Harry all year. In gratitude, Harry sticks one of his old socks into the diary and hands it to Lucius. Lucius gives the diary to Dobby, who finds the sock hidden in its pages. This constitutes, in Dobby's eyes, a gift of clothing the traditional manner in which a master frees a house-elf from servitude. The freed Dobby declares he is eternally grateful to Harry and protects him from an attempted reprisal from Lucius.

Dumbledore dispels Harry's fears that he could have been put into Slytherin rather than into Gryffindor when he tells Harry that it is his choices that define him and not his abilities, and that Harry could not have wielded the sword of Gryffindor if he did not truly belong to that house. At the end of the year feast, everyone who was petrified is revived, including Hermione, who is finally reunited with Harry, Ron, and Flick, Dumbledore announces that all the exams have been cancelled and Hagrid is released from Azkaban, and receives loud cheers and applause from everyone, except a few students of Slytherin house.

## Differences From The Book

### 1. The Worst Birthday

* The book begins in the morning of Harry's birthday. The film begins in the evening of the day the Masons' visit, omitting Dobby in the hedges and additional quarrels between Harry and the Dursleys. However Vernon does say that Harry is not thankful; Vernon says they cared for Harry since he was a baby, gave him their good food, and gave him Dudley's extra bedroom because they were so merciful.
	+ On a related note, the film implies that the Dursleys' gave Harry Dudley's old bedroom after his first year of Hogwarts, when he actually was given the bedroom right before Harry's new school year in the previous book, in an attempt to dissuade the acceptance letters to Hogwarts addressed to Harry.
* The Dursleys preparing and practicing for the Masons' visit all day is omitted, so instead they only practice in the evening before they come.
* The scene where Harry is banned by the Dursleys from saying the word "magic" is not in the film.

### 2. Dobby's Warning

* In the book, when Harry enters his room, Dobby sits on his bed quietly. In the film Dobby is jumping on his bed and laughing.
* Exactly when Dobby's banging on the wall caused Vernon to investigate and tell off Harry for ruining his "Japanese golfer joke" varies; in the book, the noise ruined Vernon's delivery of the punchline, while in the film, he was half-way through the joke.
* Dobby does not mention that Voldemort, or a possible brother, could be a suspect, as in the book version.
* In the books, whenever Dobby disapparates, the usual loud crack is heard. But in the films, Dobby appears and disappears quietly, however it differs from film to film how he does it. In this film he fades, like if the wind took him.
* The film shows Dobby levitating the cake into the sitting room and dropping it on top of Mrs Mason. In the book, however, the pudding dropped by Dobby in the kitchen, causing it to explode all over Harry, not Mrs Mason. Also in the film, Mr Mason tastes the cake, using a finger.
* While the reason in the film for the Masons' departure was due to the cake dropping on Mrs Mason, in the book it was due to Mrs Mason's fear of birds when an owl sent by the Ministry of Magic arrived at the Dursleys in regards to the illegal use of the Hover Charm that was performed.
* A scene is cut where the Ministry sends a letter to reprimand Harry for violating the Decree for the Reasonable Restriction of Underage Sorcery, which informed the Dursleys of this rule. This explains in the following film how Vernon Dursley already knew that Harry is not allowed to perform magic outside of school. Since this scene was not included in this film, it caused a continuity error with the future films.
* In the book, Uncle Vernon tells a man to fit the bars on Harry's window, but in the film, Uncle Vernon fits the bars himself.
* Harry's nightmare of himself being in a zoo cage is omitted.

### 3. The Burrow

* In the film, Ron wishes Harry a happy birthday when they fly away from 4 Privet Drive, as the Weasleys get Harry out the same evening. Ron doesn't say this in the book as Harry's birthday was the same day as the Masons visit.
* In the book, the Dursleys were woken up by Hedwig's screech. In the film, they're woken up by the noise of the bars falling into the grass.
* In the book, Harry's trunk is locked in the cupboard under the stairs and Fred and George sneak in the house and pick the lock of both Harry's room and the cupboard. In the film, Harry's trunk is in his room and Fred and George don't sneak in the house.
* In the book, Harry nearly forgets Hedwig, but he gets to her just in time. In the film, Harry doesn't forget anything.
* When Ron, Fred, and George arrive to rescue Harry, in the book they tie a rope to the bars. In the film, Ron places a large hook on a rope on the bars.
* When Harry was escaping from the Dursleys, the book states that all of the Dursleys tried to prevent him from escaping, only to end up hanging from the window. The film depicts only Uncle Vernon trying to prevent him from escaping, which results in him falling out of the window and landing into a bush. The fall of Vernon from the window was a comic effect created to make the scene more comedic.
* In the book the Weasley brothers suggest that Dobby could be an untrustworthy servant of the Malfoy. This is omitted from the film.
* In the book, when Harry arrives at the Weasleys' home, Mrs Weasley makes her sons "de-gnome" the garden. This scene is omitted from the film.

### 4. Flourish and Blotts

* The exact nature of the Floo Powder mix-up Harry underwent that sent him to Knockturn Alley varied: in the book, Harry ends up botching the pronunciation of "Diagon Alley" due to saying it amongst coughing fits due to the Floo Powder getting caught in his respiratory system. In the film, he mispronounces "Diagon Alley" as "diagonally" out of a panic thanks to watching the effect of the Floo Powder as a demonstration. On a similar note, the film doesn't require a lit fireplace to use floo powder, while the book does.
* The scene where Harry listens to Lucius and Draco Malfoy's business with Borgin is cut. It is included in the deleted scenes section of the DVD. (An alternate version of the same scene, where Harry is caught by Borgin was also filmed and included on the DVD). In this scene Lucius almost hits Draco two times with his walking stick when telling him not to touch anything. This *could* be meant in reference to the cursed necklace.
* In the book, Mr Weasley repairs Harry's glasses in Diagon Alley, but in the film, Hermione repairs them and the knowledge of her using underage magic is unnoticed. Though it is revealed in one of the following books that the Ministry of Magic only knows *where* magic is used and not *who* it is that it using magic. (This explains why Harry is believed to be the one to perform the levitating spell on the pudding through it is Dobby).
* The part where Arthur Weasley fights with Lucius Malfoy in Flourish and Blotts is omitted. Instead, they only exchange tense words. Lucius also mentions that he will "see you [Arthur] at work," implying that he works at the Ministry of Magic, or at the very least has visited the Ministry enough times that he and Arthur have interacted to some extent there. On a related note, Lucius only subtly puts the diary into Ginny's cauldron after looking at and mocking her hand-me-down textbook in the film. In the original, he gives the book back to her after fighting her father, the diary stealthily included in it, after the fight.
* When they meet in Diagon Alley, Hermione chides Lucius Malfoy for not using Voldemort's name. (In the first two films, Hermione shows no fear of the name Voldemort, speaking with without difficulty in the first film). In the books, Hermione never uses the name Voldemort until the fifth novel, and even then it requires courage. The films have a bit of a continuity issue on this point as the fifth film shows her getting the courage to say "Voldemort."
* Arthur Weasley asks Harry about escalators in the book, but in the film he asks about rubber ducks and plug holes.

### 5. The Whomping Willow

* Harry and Ron get to Hogwarts with almost no problem in the book, whereas in the film they nearly get hit by the Hogwarts Express, and Harry nearly falls out of the car.
* In the film, Argus Filch finds Harry and Ron and takes them to Professor Snape's office, but in the book, Snape himself finds Harry and Ron and takes them to his office (with Harry and Ron noticing his absence from the Great Hall professors' table just prior to Snape revealing himself to them).
	+ In a deleted scene that follows this scene Harry finds a letter about a Kwikspell course addressed to Filch and hands it over. In the book Flick is with him and they find the letter in Filch's office.
* In the book, Ron and Harry eat sandwiches in Snape's office after being caught by Snape. Ron wants to know which house Ginny was placed in and Professor McGonagall tells him she's a Gryffindor. This scene is not in the film, but Ron does find out about Ginny being in Gryffindor from his mother's howler.

### 6. Gilderoy Lockhart

* In the book, Mrs Weasley's Howler to Ron is much lengthier and mentions Harry in it. In the film the Howler message is much shorter and Harry is never mentioned, instead a part of the Howler was directed to Ginny. Also in the book, there is no mention of Howlers folding themselves into a pair of lips.
* The Howler bursts into flames in the book but rips itself into shreds in the film.
* Lockhart's scene with Professor Sprout before the first Herbology lesson of the year, in which he implied that he knew more about caring for Whomping Willows than she did, is not shown.
* The scenes in which Lockhart lectures Harry for giving out autographs (due to Colin's actual request in the book) and makes him late for Herbology, are not seen in the film.
* In the film, Neville Longbottom faints when the Mandrakes are shrieking, and Professor Sprout remarks that he has been "neglecting his earmuffs." This scene does not happen in the book.
* Defence Against the Dark Arts shows both Hufflepuffs and Slytherins in the same class as the Gryffindors.
* Second-year Gryffindors have Herbology only with the Hufflepuffs in the book, but also with the Slytherins in the film.
* When the Pixies are loose in Lockhart's class, there are several differences that occur:
	+ In the novel, several pixies shoot straight through the window, showering the back row with broken glass. The rest proceed to wreck the classroom more effectively than a rampaging rhino, grabbing ink bottles and spraying the class with them, shredding books, tearing pictures from the walls, upending the bin, grabbing bags and books and throwing them out of the smashed window: within minutes, half the class were sheltering under their desks and Neville was swinging from the iron chandelier, before the bell rings and everyone leaves. In the film, the chaos consists of book throwing, tearing pages out of books and hanging Neville onto the chandelier. Also in the film, no one hides under the desks and everyone leaves on their own accord to save themselves from the Pixies.
	+ The Pixies throw Lockhart's window in the book. In the film, this does not happen and instead, one of the Pixies snatches Lockhart's wand and breaks off the dragon skeleton hanging from the ceiling.
	+ Also in the film there is an added moment when the Pixies steal a portrait of Lockhart and he tries to get it back, but fails.
	+ In the novel, Lockhart hides under the desk, but in the film, he doesn't. Also Neville falls from the chandelier in the book and misses Lockhart. In the film, Neville remains hanging from the chandelier, with him humorously lamenting why these situations always happen to him.
	+ In the novel, Harry, Ron, Flick, and Hermione are almost at the door but Lockhart stops them and asks them to try and nip the rest of them back into their cage, but in the film, the quartet just remain a distance from the door and try to stop them until Hermione immobilises all the Pixies.
	+ In the film, Lockhart runs into his office, while in the book, he ran through a door, but it is not specified which door it is.
	+ In the novel Hermione freezes several pixies and then sends them back to their cage. In the film, she paralyses all the Pixies and is never shown putting them back into their cages.
* Ernie Macmillan's role is diminished to a non-speaking part. The part where he and Hannah Abbott talk in the library about their theory of Harry wanting to attack Justin Finch-Fletchley was cut, but appears on the deleted scenes, however in the Study Hall. Also, Ernie is the one who blames Harry for attacking Justin when he is discovered, petrified, but in the film, Argus Filch finds Harry and wants to expel him. In the book, it was Peeves who found him, and sung his funny song.
* As with the previous film and all of the following ones, the character of Peeves is omitted completely.
* During the first Defence Against the Dark Arts lesson, Lockhart refers to the Bandon Banshee as male rather than female.
* The scene where Lockhart gives out a test is omitted in the film. It is included as a deleted scene on the DVD of the film.

### 7. Mudbloods and Murmurs

* In the book, Hermione has never heard the term "Mudblood" before, and Ron and Flick explain the term to her and Harry. In the film, she is aware of the term and is deeply hurt, even seen trying not to cry, and explains what it means to Harry, though Hagrid defines its origin for Harry and says exactly what Ron and Flick say in the book. Flick only responds to it with only two words, and Ron is unable to say anything as he is in the middle of throwing up slugs.

### 8. The Deathday Party

* Nearly-Headless Nick's Deathday Party does not appear in the film, other than in concept art. Because of this, Harry encounters the petrified Mrs Norris on his way back from spending hours of detention with Gilderoy Lockhart instead. Harry also meets Ron, Flick and Hermione just before finding Mrs Norris in the film, while in the book they were with Harry the entire time.

### 9. The Writing on the Wall

* In the book, Harry, Ron, Flick and Hermione are interrogated by the teachers in Lockhart's office. The film moves the interrogation to the corridor where the attack happened.
* Mention of Filch being a Squib is omitted.
* Mention of Ron's detention and the fact that he recognised Tom Riddle's name from an award he received for special services to the school was cut, but appears on the deleted scenes.
* In the film, Hermione claims that the message on the wall is written in blood. The book, however, states that the message is simply written in red paint.
* In the film, it is Professor McGonagall who tells the class about the history of the Chamber of Secrets instead of Professor Binns.
* Because of the scene with Harry first hearing the Basilisk being moved to during his detention with Lockhart instead of while heading back from the Deathday Party, the teacher's interrogation of the quartet was altered:
	+ Snape is not supporting Filch's claims just like in the book where he does in order to punish Harry. The film depicts him announcing to the teachers that the quartet were simply present at the wrong place at the wrong time, implying that he may have been vouching for Harry's innocence.
	+ Snape also views Harry in particular as a suspect due to the latter's absence during dinner before Lockhart admits causing Harry's absence; unintentionally having Harry stay beyond the intended time period for detention. Flick explains to the teachers that her, Hermione and Ron's absence after they noticed that Harry was missing and they tried to search for him. Harry was about to mention about hearing the basilisk's voice before trailing off, but then feigns of replying that he wasn't hungry and adds that they found Mrs Norris while on the way to the common room.
* In the book, Flick is adamant that Malfoy is not the Heir of Slytherin, whereas in the film she agrees with the others that it could be him.

### 10. The Rogue Bludger

* In the book, to borrow the Moste Potente Potions book from the library, which had the recipe for Polyjuice Potion, Hermione had to get a note from Lockhart (which he signed without looking at) because it was in the restricted section. In the film, the scene was omitted, and the book was in the regular section of the library.
* In the film, the match takes place in sunlight; in the book, the majority of it takes place in rainy weather.
* In the book, Draco does not notice the Snitch at all, due to having been insulting Harry at the time and Harry quickly catches the Snitch before Malfoy could realise it, but in the film, he sees it just after Harry does, and just after ducking to prevent being hit by a Bludger, and it leads to both of them chasing after the snitch for a few seconds before Harry catches it first. Also in the film, they chase the Snitch in between the Quidditch Stands.
* During the match in both book and film, Slytherin had taken the lead of Gryffindor of throwing the Quaffle through the hoops, but they had different scores; in the book, the final score was 60-0, but in the film, the score is 90-30, in which Gryffindor would then receive 150 points because Gryffindor won the match.
* In the film, while Malfoy was dodging the Bludger, he tilted his broom too low, the tip of his broom hits a beam, causing him to catapult off his broom, and land on the grass, doing a full split. He was still moaning in agonising pain at the Hospital Wing when Madam Pomfrey tells him not to make such a fuss.
* In a deleted scene from the film Harry tries to avoid being hit by a Bludger by flying in the Slytherin tribune. This does not happen in the book.
* Lucius Malfoy is seen in the audience observing the Gryffindor-Slytherin match in the film. This is not mentioned in the book.
* In the book Fred and George attempt to protect Harry from the rogue Bludger, and later place it back in its case while restraining it. In the film, Hermione destroys the rogue Bludger with Finite Incantatem after the game, effectively damaging a piece of Hogwarts property.
* In the book, Harry's arm is injured by the Rogue Bludger, before he charges at Malfoy, but after spotting the Snitch, due to a moment of hesitation. In the film it occurs after the added incident in which Malfoy has crashed off his broom. Additionally Hagrid is present when Lockhart removes the bones from Harry's injured arm when attempting to heal the broken bones, whereas he wasn't in the book.
* In the film, Filch supports Slytherin, being seen standing in a crowd of Slytherin spectators just like in the first film, whereas in the books is is never specified if he takes sides.
* In the book, when Harry is in the hospital wing following the Quidditch match, Ron, Flick, Hermione and Madam Pomfrey are the only people there when he takes the Slele-Gro, the rest of the team come in later and Madam Pomfrey shouts at them to leave. In the film the entire team plus Ron and Hermione come with him, and Madam Pomfrey tells them to clear her way.

### 11. The Duelling Club

* The scene in which Harry, Ron, Flick and Hermione cause a disturbance in Potions to steal ingredients from Snape was omitted. This caused a continuity error for the *Harry Potter and the Goblet of Fire* where Snape accuses Harry of brewing Polyjuice Potion by stealing its ingredients "again." Possible explanations could be that it happened off-screen, or that Snape just came to the conclusion that Harry did it. Also, because Barty Crouch Jr. was stealing Snape's ingredients to brew Polyjuice Potion to impersonate Alastor Moody in the fourth film, it is possible that Snape mistakenly thought Harry was stealing the ingredients earlier in his fourth year and was warning him not to do so in what Snape falsely perceived to be a second time.
* In the Duelling Club scene, Harry and Draco are the only combatants participating, while in the novel, other classmates in their year are shown participating along with them, such as Hermione, Millicent Bulstrode, Flick, Pansy Parkinson, Ron, Seamus, Neville, and Justin Finch-Fletchley.
* Also in the Duelling Club sequence, when Harry speaks Parseltongue, in the book, the reader knows what he says immediately, as is the case when Harry speaks with the snake at the zoo in the film version of *Philosopher's Stone*. In the film, it's only hissing sounds until Harry explains what he said to Ron, Flick and Hermione. Other uses of the language later in the film are left untranslated, but most likely are the same as the book's translations.
* A line that Snape spoke in the book "Longbottom causes devastation with the simplest spells," was changed to "Weasley's wand causes devastation with the simplest spells" after Lockhart chose Ron and Harry to demonstrate the Disarming Charm (in the book, Snape spoke instead about Neville Longbottom). The film also changed the line "We'll be sending what's left of Finch-Fletchley up to the hospital wing in a matchbox" to "We'll be sending what's left of Potter up to the hospital wing in a matchbox" as Justin Finch-Fletchley did not duel during the scene, either.
* Also in the Duelling Club scene, Rictusempra was used like a Stunning Spell which caused Malfoy to be thrown up in a back flip. In the book, Rictusempra was described to give its receiver an uncontrollable tickling sensation. Tarantallegra, a jinx used to force someone to dance wildly and involuntarily, was also not used in the film. In addition, attacking with a Serpensortia spell was Malfoy's own choice, whereas in the novel, Snape was the one who gave him the idea. Everte Statum was also not mentioned in the book but was used in the film.
* In the film, Moaning Myrtle appears while Harry, Ron, Flick and Hermione are brewing the Polyjuice Potion. In the book she appears much earlier, at Nearly-Headless Nick's Deathday Party.
* In a deleted scene after the Duelling Club, Harry was talking to Hedwig in a mountainous area away from the castle saying "Who am I, Hedwig? What am ?"

### 12. The Polyjuice Potion

* In the book, when Harry asks the Sorting Hat whether it put him in the right house, he does it with the hat on his head. In the film, he merely stands before it.
* The Polyjuice Potion in the book changes colours as the hair is added. In the film, it does not change colour at all.
* The scene in the Great Hall during the Christmas Feast, Flick and Hermione simply say that they got Pansy Parkinson's and Millicent Bulstrode's hairs off their robes. The novel, however, depicts them a finding the hairs while during Duelling Club while they were fighting.
* The scene where Harry and Ron hide Crabbe and Goyle in a broom cupboard is omitted (the scene was filmed and included in the deleted scenes section, though). Due to this omission Crabbe and Goyle are dazed and confused when Harry, Ron and Flick run past them after their transformation has worn off instead of pounding while still in the cupboard.
* In the novel, the potion is in one of the stalls and when the quartet prepares to drink from their separate glasses, they each go into a different stall and drink. In the film, the potion is in one of the sinks and the quartet drink beside that same sink and only Ron, Flick and Hermione run into cubicles when they feel they're going to be sick (not said in the book) while Harry remains at the sink and watches himself transform.
* In the book, Harry feels his insides start writhing as though he'd just swallowed live snakes - doubled up, then a burning sensation spreads rapidly from his stomach to the very ends of his fingers and toes - next, bringing him gasping to all fours, then comes a horrible melting feeling, as the skin all over his body bubbles like hot wax - and before his eyes, his hands began to grow, the fingers thickened, the nails broadened, the knuckles were bulging like bolts - his shoulders stretched painfully and a prickling on his forehead told him that hair was creeping down toward his eyebrows - his robes ripped as his chest expanded like a barrel bursting its hoops - his feet were agony in shoes four sizes too small. In the film, Harry watches his hands bubbling and then looks into the sink's mirror and watches his face bubbling then turning into Goyle's face.
* The effects of the Polyjuice Potion differ from book to film. In the film, Harry, Ron and Flick's voices don't change when they become Crabbe, Goyle and Parkinson, forcing them to imitate their voices. This was presumably done to avoid confusing the audience because of the change in appearance which would be the standard for the use of the potion in both of the Deathly Hollows films.
	+ This causes a continuity error with Barty Crouch Jr.'s usage of the Polyjuice Potion in *Harry Potter and the Goblet of Fire* as his voice does change when he becomes Moody, though this can be considered as an exception as his identity was kept secret until the end of the film.
* In the book, Harry's vision changes and he takes his glasses off after using the Polyjuice Potion, but in the film, his vision apparently does not change, and only takes the glasses off when Draco questions Harry (here disguised as Goyle) wearing them.
	+ This could also create a continuity error in the film adaptation of first half of *Harry Potter and the Deathly Hallows* when Hermione, Flick, Ron, and others take the potion to transform into Harry, and Hermione remarks that Harry's eyesight is really bad.
* During the Slytherin Common Room scene, there are some parts of the book which are omitted from the film, like:
	+ Draco showing Goyle/Harry, Crabbe/Ron, Parkinson/Flick the *Daily Prophet* article about Arthur Weasley's inquiry at the Ministry of Magic about having been fined for having an enchanted Muggle car is omitted.
	+ Draco does not mention Dumbledore's love of Muggleborns (but it's obvious that Dumbledore still loved them). Also, due to this omission, Draco does not make the rude mimicking act of Colin Creevey wanting Harry's autograph.
	+ There is no mention of Azkaban in this scene because Harry did not ask Draco whether he knew if the person who opened the Chamber last time was caught. Instead, it is first mentioned by Hagrid in the scene where Dumbledore and Cornelius Fudge come to Hagrid's hut.
* In the film, when Draco mentions that "you'd never know" the Weasleys were Purebloods the way they behave along with an added line that was not mentioned in the book - "They're an embarrassment to the wizarding world. *All* of them." - Ron makes a fist and looks furious, but in the book, Ron's face is just contorted with fury and there is no fist.
* In the book, Flick, Ron and Harry realise they're turning back to normal when Harry sees Ron's hair turning red and his nose lengthening and they run. In the film, they realise when Flick sees Harry's scar reappearing (which didn't happen in the book), Harry sees Ron's hair growing red again, and Ron sees Flick's eyes turning blue and whispering "Scar" (Flick), "Hair" (Harry), and "Eyes" (Ron).
* There is a scene added in which Draco finds a small package and after shaking it once, asks Goyle/Harry if it's his. Harry shakes his head and Draco puts the package in his pocket, then a few seconds before Harry, Ron and Flick realise they're about to turn back to their normal selves, Draco unwraps the package and after the trio start turning back to normal, Draco is seen to have a small silver object in his hand, but it does not fully appear since it was in Draco's hand. The package was not included in the book.

### 13. The Very Secret Diary

* The part where Hermione gets a get well soon card from Lockhart is omitted, but included in the original script.
* In the book, Professor Binns explains to the class about the Chamber of Secrets during a History of Magic class. The film makes a different depiction and has Minerva McGonagall explain it during a Transfiguration class. Professor Binns is omitted in the film.
* The Valentine's Day breakfast in the Great Hall which was arranged by Lockhart is omitted.
* The scene where Harry gets his Valentine and Malfoy tries to steal Riddle's diary in which Harry disarms him and Percy scolds Harry for using magic in the corridors is omitted.
* In the book, the ink is scarlet. In the film, the ink is black.
* In the book, Tom Riddle's diary displays his first and middle names as initials. In the film, Tom Riddle's full first and last names are shown on the diary.
* In the book, when Harry gets sucked into the diary to 1943, he enters through the Headmaster's Office where Professor Dippet was reading a letter from Tom Riddle. In the film, he enters below the Grand Staircase where Tom Riddle was standing, shortly before a younger Dumbledore appears to talk to him.
* In the film, a scene is added in which Harry and Tom Riddle see Myrtle's dead body (unknown to Harry) wrapped up in a sheet with her right arm sticking out and being carried away by several unidentified wizards. This event did not occur in the novel.
* In the book, Armando Dippet is the one to talk to Tom Riddle about Hogwarts closing. In the film, Dumbledore talks to Rom while Dippet appears only a brief second then turns his back and does not speak to Tom. Although, in the book, after Tom's meeting with Dippet, he finds Dumbledore who asks Tom why he's wandering around late and then tells him to hurry off to bed because it's not safe to roam the corridors these days.
* In the book, while Harry is in the memory inside the diary and he sees Tom Riddle with Rubeus Hagrid, Tom calls him "Rubeus," but in the film he calls him Hagrid instead, like everybody else.
* The dwelling of Aragog is a treasure chest-like box as opposed to a cupboard.

### 14. Cornelius Fudge

* In the book when McGonagall is cancelling the Gryffindor-Hufflepuff Quidditch Match, she is doing this with a large megaphone while out on the field to send the message much to the dismay of Oliver Wood and the audience. In the film however, she simply informs the Gryffindor team just as they were heading out to the field, and Wood is much less aggressive about it than in the book.
* Ginny's attempt to confide her secret to Ron, Harry and Flick is omitted, although a scene where Ginny sees Harry with the diary was initially featured in the script.
* Almost all foreshadowing hints about Ginny acting strangely or emotionally are omitted. However, in the film, the scene in which McGonagall informs the Gryffindors of the possible closing of the school reveals a close-up of Ginny appearing uneasy as if it's her fault.
* Penelope Clearwater's role as a Basilisk victim is omitted from the film.
* The book mentioned that "*the crowing of the rooster is fatal to the Basilisk*" which led Hagrid's roosters to be killed since the Heir of Slytherin didn't want one near the castle. This was not mentioned in the film, although Hagrid was seen holding one of his dead roosters when bursting into Dumbledore's office in an attempt to defend Harry from being expelled before realising Dumbledore doesn't even think Harry's at fault for what had happened with Mrs Norris, Colin Creevey, Justin Finch-Fletchely, and Nearly-Headless Nick. A deleted scene shows Harry finding Hagrid holding the rooster. Hagrid explains his thought about a Blood-Sucking Bugbear, and that he is going to ask Dumbledore for permission to cast a protection charm.

### 15. Aragog

* In the book, after Hagrid mentions that if they were looking for answers, all they'd have to do was follow the spiders, Harry, Ron and Flick didn't see any spiders until one day in Herbology when Harry points them out. They noticed the path the spiders were taking, which was right into the Forbidden Forest, and didn't follow them until everyone had gone to sleep in their dormitory. In the film, right after Hagrid is taken away by the Ministry, the trio see spiders crawling along Hagrid's window and follow them into the Forest.
* In the book, Ron (reluctantly), Flick and Harry looked around for spiders and then when entering the forest, Ron is brave. In the film, Ron is completely scared and reluctant to go into the forest and follow spiders.
* In the film, Ron asks why they have to follow spiders and why it could not be "Follow the butterflies." This dialogue did not appear in the book.
* In the book, Harry, Ron, Flick and Fang are taken by the spiders to Aragog's lair but in the film they make their own way there. Also, they never see the Ford Anglia before arriving at Aragog's lair; hence their looks of surprise in the film when it crashes through the spiders to rescue them, although a deleted scene shows them finding the car before they meet Aragog.
* Also, in the deleted scene where the trio find the Ford Anglia, Harry tells the others they don't want to lose the trail of spiders, but in the book, they lose the trail and try to find them before being dragged to Aragog's lair.
* In the film, Mosag, Aragog's mate, is not mentioned.

### 16. The Chamber of Secrets

* In the book, Harry deduces and tells Ron and Flick that the girl who died in the fifth-floor bathroom was most likely Moaning Myrtle due to her "never leaving" there, before Flick finds the scrap of paper in the petrified Hermione's hand detailing the Basilisk as well as her personal note as to how it was travelling through the school, immediately after returning from the Forbidden Forest. In the film, Harry tells Ron and Flick this after finding the paper himself, just before McGonagall announces for all the students to return to their dormitories immediately.
* In the book, when McGonagall and the other teachers volunteer Lockhart to fight the Basilisk, the teachers are collected in the Staff Room with Harry, Ron and Flick hiding in the wardrobe. In the film, the teachers are gathered in front of the daubed message on the wall stating Ginny's capture with the trio hiding behind a corner. Also, in the book the teachers' comments after Lockhart has left them make it clear that they know he is incapable and were simply getting him out of the way. These comments are left out from the film, but it's still highly unlikely the plan was ever genuine.
* In the book, when the trio realise that Lockhart is a fraud, they subdue him by performing a Disarming Charm and throwing his wand out of the window. In the film, Lockhart drops his wand in a manner of defeat, when Harry, Ron and Flick point theirs at his face.
	+ Also, the book has Lockhart citing some specific examples of individuals that he not only stole credit for their deeds from, but also wiped memories from as insurance. The film does not actually list any specific examples of his victims.
* In the film, just before Harry, Ron and Flick jump into the giant pipe leading to the Chamber of Secrets upon opening it, Moaning Myrtle offers to let Harry share the toilet she lives in should he die in the chamber. She only alludes to this offer in the book *after* Harry, Ron, Flick, Ginny, and a recently-amnesiac Lockhart leave the chamber, where se expressed some implied disappointment in the fact that Harry survived.
* In the book, it says that the snake who had shed the skin must have been at least twenty feet long. In the film, Ron remarks that the creature must have been at least sixty feet long.
* In the book, Harry walks for a longer period through the tunnel to find the Chamber after being separated from Ron, Flick, and Lockhart, but in the film, the tunnel was only one small room and had the entrance to the Chamber right before Harry, Ron, Flick and Lockhart. Although, before they enter the room, there is another passage seen on the opposite side.
* In the book, the entrance to the Chamber where Ginny was consisted of a solid wall on which two entwined serpents are carved, their eyes set with great, glinting emeralds and when Harry speaks Parseltongue to open the entrance, the serpents part as the wall cracks open and the halves slide smoothly out of sight. In the film, the entrance consisted of a circular door with 7 snakes on it that were on the edge of the door and when Harry speaks Parseltongue to open the entrance, an eighth snake appears from the cylinder bit where the snakes are held and goes all around the door and whenever it approaches each snake's head, the snake's head backs away and allows the door to be opened.

### 17. The Heir of Slytherin

* In the film, Harry, shortly after Riddle rearranged his name to unveil his true identity as Lord Voldemort, explicitly states the latter's the Heir of Slytherin. Harry does not do so in the book, though it was nonetheless made very clear what Riddle/Voldemort's connection to the Heir of Slytherin was.
* In the film, the Basilisk is seen chasing Harry all around the Chamber of Secrets whereas in the book, Harry's fight against the Basilisk occurs quickly and neatly. In the book, Harry never climbs up the statue nor does he go into the statue.
	+ In addition, Tom Riddle's reaction throughout the fight in the film was significantly calmer compared to the book. In the film, outside of yelling "No!" in shock and stating that the Basilisk can still use its other senses (see below), he does not react in any way to the Basilisk missing Harry. In the book, Tom Riddle is repeatedly yelling at the Basilisk to smell Harry when it is repeatedly missing Harry in their fight.
	+ The film also has Riddle claiming that Harry Potter's parseltongue abilities are of no use against the Basilisk, as it was specifically trained to only obey him, something that was not in the book (and which conflicted with the revelation later on that Harry Potter was one of Voldemort's horcruxes).
* The Chamber has a different depiction
	+ The statue at the end of the Chamber of Secrets is a full body statue of Salazar Slytherin, while in the film it is only a large statue of Slytherin's head and shoulders. The book *Harry Potter Page to Screen: The Complete Filmmaking Journey*, has Rowling reveal that the Chamber is flooded centuries after its creation and the rest of the statue below his head is submerged beneath the water. This also explains why the Basilisk was seen emerging from the water near the statue when Harry attempts to wake the nearly-dead Ginny.
	+ In the book, pillars hold up the ceiling of the Chamber of Secrets. In the film, there is nothing to hold the ceiling up (although two pairs of pillars do appear in the game version in the) but it shows that there were two lines of giant statues of snakes' heads where the pillars were in the book. It is also possible that the original Chamber hall is submerged along with the original pillars and that the snake head statues are the remainders of the pillars.
* In the book, after Fawkes had punctured the Basilisk's eyes, Riddle stated that it can still smell Harry. In the film, Riddle stated that it can hear him.
* In the book, Fawkes uses his tears to heal Harry while Riddle is still alive, but in the film Fawkes does not use his tears to heal Harry until *after* Riddle's destruction, as such Ginny wakes up and sees the dying Harry.
* In the book, in the Chamber of Secrets, Harry puts on the Sorting Hat and shouts at it for help. The sword then comes out and hits him on the head, nearly knocking him out. In the film, the sword just all of a sudden materialises in the hat when it's just lying on the ground, and Harry takes it.
* In the book, Harry Potter only destroyed the diary with the basilisk fang after he was healed by Fawkes. In the film adaptation, Harry destroyed the diary with the fang *before* he was healed.
	+ In addition, the book only mentioned that Riddle's memory writhed and then faded away after the diary was destroyed, while in the film, it was shown that Riddle's memory's chest cavity ripped open with light, then destroying his eyes and causing damage to his face, before eventually causing gaping holes throughout his body upon exploding.
	+ Lastly, Harry Potter only stabbed the diary once in the book, while in the film, he stabbed the diary three times, two being in two different sections of the book, and the last from the outside.
	+ A Star Wars reference is included in the scene where the diary is destroyed. During the first and second stabs, as light bursts out from Riddle, the sound of an igniting lightsaber is heard.
* The film has Ginny reacting in a significantly calmer manner when awakening shortly after Tom Riddle's memory was destroyed than in the book. In the latter, in addition to admitting her unwilling role in the disaster, Ginny clearly was breaking down from the entire ordeal. Similarly, because of the switching around of Fawkes healing Harry and the destruction of the diary (see above), Ginny also notices that Harry was injured, something that was not the case in the book.
* In the book, when Harry and Ginny find Ron, Flick and Lockhart, Lockhart (having lost his memory) says "Hello," that the chamber is an odd sort of place and asks if the four live there to which Ron answers "No." In the film, this occurs before Harry enters the Chamber and finds Ginny and Lockhart having just caused the tunnel to collapse. He says "Hello," asks Ron and Flick who they are, to which Ron replies "Um... Ron Weasley," and Lockhart responds, "Really? And who am I?". Flick then says to Harry through the gap hole of the rocks that Lockhart's Memory Charm backfired and that he hasn't got a clue who he is. Lockhart then picks up a stone, gives it a short throw and asks Ron if he lives in the Chamber (also also gives the stone to Ron) to which Ron replies "No." and Lockhart replies "Really?" and then Ron does something he never did in the book; he hits the stone on the top of the left side of Lockhart's head and he falls back down (presumably unconscious).
* The departure from the Chamber is depicted differently in the film and the book by the end of the characters' journey with Fawkes.
	+ The book states that the journey ends in Moaning Myrtle's bathroom in the morning, where the entrance seals shut again, and they head to McGonagall's office.
	+ The film shows that the characters are carried by Fawkes to a cave entrance in a cliff wherein a full moon gleams and they land onto the grounds of Hogwarts, then head to Dumbledore's office. The landing at the Hogwarts grounds and heading to the Headmaster's Office is done off-screen.

### 18. Dobby's Reward

* In the film, when Lucius arrives at Dumbledore's office and Harry notices Dobby, he is shown realising that Dobby's masters were the Malfoys and thus explained why he was hesitant to reveal anything directly or his self-inflicted punishments, with Lucius then giving a veiled threat to the house elf in response. This did not happen in the book (largely because Dobby had already been speculated to be part of the Malfoy family much earlier in the book).
* In the book, Harry's conversation with Dumbledore after the defeat of the basilisk is set in McGonagall's office, and Arthur, Molly, and McGonagall are present at the start of the scene. In the film, the scene is set in Dumbledore's office instead, and Arthur, Molly, and McGonagall do not appear.
* In the book, Harry accused Lucius of deliberately supplying the diary to Ginny Weasley at Diagon Alley while they were still in Dumbledore's office and Lucius is meeting with Dumbledore due to Dobby's nonverbal hints, with Dumbledore also giving a veiled threat to Lucius in response to this as well as his forcing the board of directors to sack Dumbledore. In the film, Harry's accusation occurs after Lucius leaves (although still due to Dobby's nonverbally hinting at Lucius's connection to the diary before departure), and Dumbledore, while still implicitly warning Lucius about his actions with the diary, is not notified by Harry about Lucius's action with the diary.
* In the film, Lucius Malfoy's sarcastic statement about Harry and Harry's response was improv from the actors.
* In the book, to free Dobby, Harry puts the diary in his sock and had Lucius Malfoy throw it so Dobby would catch it after he removed the diary, but in the film Harry puts his sock in the diary and had Lucius give the diary with the sock to Dobby unknowingly instead.
* In the book, just after Dobby was freed, Malfoy raises his wand threateningly at Harry, before Dobby tells him to leave. In the film, it sounds like Lucius Malfoy starts saying "Avada Kedavra" before Dobby blasts him backwards across the hall (the spell was the result of an ad-lib by Jason Isaacs).
* In the book, Lucius Malfoy says to Harry, "Someday you'll meet the same sticky end as your parents. They were meddlesome fools too." In the film, he said, "Your parents were meddlesome fools, too. Mark my words, Potter - one day soon, you're going to meet the same, sticky end."
* During the dinner scene, the scene where Gryffindor wins the House cup again is cut, though it is nonetheless implied.
	+ Hermione originally hugged Harry, Ron and Flick in the book upon revealing that she had been cured. In the film, she only hugs Harry and Flick, and just gives a hesitant handshake to Ron (note, this was the result of Emma Watson being hesitant to hug both Daniel Radcliffe and Rupert Grint in public view, with her hugging Radcliffe during filming having to be frozen for a few seconds to get the desires effect due to Watson breaking the hug too quickly). This also unintentionally foreshadowed her and Ron's hesitant blossoming feelings for each other in the succeeding films.
	+ In addition, Hagrid's arrival has him apologising for his lateness, explaining his release from Azkaban was delayed due to the letter requesting his release getting lost, and proceeding to blame a bird named Errol for it getting lost, causing Ron to give a slightly embarrassed look. This was not present in the book.
