Title: Rubeus Hagrid
Content:  In Philosopher’s Stone, Hagrid is mentioned as being twice as tall as the average man and nearly five times as wide but in the film, he is portrayed as being 8ft 6in and in later books he is said to be three times as wide. Hagrid is known for his thick West Country accent. Being a half-giant, he is less vulnerable to jinxes and spells than full-humans. In Order of the Phoenix, when Umbridge and some other wizards come to remove him from Hogwarts he fights back. They try to jinx and stun him, but the spells just bounce off him because of giant-inherited resistance to magic. Hagrid also shows this resilience at the end of Half-Blood Prince, during the chapter Flight of the Prince, withstanding a Death Eater’s powerful curses. Some potions are also ineffective with him, such as Polyjuice Potion, which is designed for human-only use.
Title: Rubeus Hagrid
Content:  Rubeus Hagrid is a fictional character in the Harry Potter book series written by J. K. Rowling. He is introduced in Harry Potter and the Philosopher's Stone as a half-giant and half-human who is the gamekeeper and Keeper of Keys and Grounds of Hogwarts, the primary setting for the first six novels. In the third novel Harry Potter and the Prisoner of Azkaban, Hagrid is promoted to Care of Magical Creatures professor, and is later revealed to be a member of the Order of the Phoenix. A loyal, friendly, softhearted personality who is easily brought to tears, he is also known for his thick West Country accent. Hagrid is portrayed by Robbie Coltrane in all eight Harry Potter films, from Philosopher's Stone in 2001 to Deathly Hallows – Part 2 in 2011.

Content:  role. She also stated that "Robbie is just perfect for Hagrid because Hagrid is a very loveable character, quite likeable, quite comic [...] but he had to have – you really do have to sense – a certain toughness underneath [...] and I think Robbie does that perfectly." Former English rugby union player Martin Bayfield portrayed Hagrid as a stunt performer in longer shots due to his large size to emphasise Hagrid’s height. Bayfield also appeared as a young Hagrid in Harry Potter and the Chamber of Secrets. English actor Greg Draven portrayed Hagrid as an acting double in Hagrid's Magical Creatures Motorbike Adventure. Draven's performance was required due to Robbie's poor health at the time of filming.
Title: Forced perspective
Content:  Forced perspective has been employed to realize characters in film. One notable example is Hagrid, the half-giant in the Harry Potter series. The technique is used in the Lord of the Rings series for depicting the apparent heights of the hobbit characters, such as Frodo, who are supposed to be around half the height or less of the humans and wizards, such as Gandalf. In reality, the difference in height between the respective actors playing those roles is only 5 in, where Elijah Wood as the hobbit Frodo is 5ft 6in tall, and Ian McKellen as the wizard Gandalf is 5ft 11in. The use of camera angles and trick scenery and props creates the illusion of a much greater difference in size and height. Numerous camera angle tricks are played in the comedy film Elf (2003) to make the elf characters in the movie appear smaller than the human characters.
Title: Rubeus Hagrid
Content:  Grawp is the giant half-brother of Hagrid. Grawp and Hagrid were born of the same mother, the giantess Fridwulfa. Grawp is about 16 ft tall, which Hagrid claims is small for a giant. His knuckles are the size of cricket balls (~225 mm in circumference). The other giants were bullying Grawp because of his diminutive size, and this is a factor in Hagrid’s decision to bring him to the Forbidden Forest. Big and dim, he only knows a few words in English and his manners are wild and unpredictable, but he is also a child in giant years. In the film, this is elaborated on more as he is 
Title: Rubeus Hagrid
Content:  Scottish actor Robbie Coltrane has portrayed Hagrid in all of the film adaptations of the Harry Potter novels. Robin Williams was interested for the role and approached Chris Columbus, the director of the first two films, about participating in the project but Columbus rejected him due to the "all-British and Irish cast" policy. Rowling had wanted Coltrane for the role from the start, responding "RobbieColtraneforHagrid" all in one quick breath when asked who was the top of her list of casting choices. Coltrane was already a fan of the books and has commented that being part of the Harry Potter franchise was "a fantastic thing." Rowling discussed Hagrid's past and future with Coltrane, assisting him in preparing for 
Title: Harry Potter (film series)
Content:  Aside from the three lead actors, other notable cast members include Robbie Coltrane as Rubeus Hagrid, Tom Felton as Draco Malfoy, Alan Rickman as Severus Snape, and Dame Maggie Smith as Minerva McGonagall. Richard Harris, who played the role of Professor Albus Dumbledore, died on 25 October 2002 causing the role to be re-cast for the third instalment, Harry Potter and the Prisoner of Azkaban. David Heyman and director Alfonso Cuarón chose Michael Gambon to portray the character of Dumbledore, which he did for all succeeding films. Notable recurring cast members include Helena Bonham Carter as Bellatrix Lestrange, Warwick Davis as Filius Flitwick, Ralph Fiennes as 
Title: Harry Potter (character)
Content:  Harry James Potter is a fictional character and the titular protagonist in J. K. Rowling's series of eponymous novels. The majority of the books' plot covers seven years in the life of the orphan Harry, who, on his eleventh birthday, learns he is a wizard. Thus, he attends Hogwarts School of Witchcraft and Wizardry to practise magic under the guidance of the kindly headmaster Albus Dumbledore and other school professors along with his best friends Ron Weasley and Hermione Granger. Harry also discovers that he is already famous throughout the novel's magical community, and that his fate is tied with that of Lord Voldemort – the internationally feared Dark Wizard and murderer of his parents, Lily and James. The book and film series revolve around Harry's struggle to adapt to the wizarding world and defeat Voldemort. Harry is regarded as a fictional icon and has been described by many critics, readers, and audiences as one of the greatest literary and film characters of all time. He is portrayed by Daniel Radcliffe in all eight Harry Potter films from Philosopher's Stone (2001) to Deathly Hallows – Part 2 (2011).
Title: Production of The Lord of the Rings film series
Content:  (1.68 m) tall in real life, but his character, Frodo Baggins, is only 3 ft 6 in (1.07 m) in height. John Rhys-Davies, who played the Dwarf Gimli, is taller than Wood. Thus in the ending shot of the Council of Elrond scene, when all nine members of the Fellowship of the Ring are standing together, Rhys-Davies and the four Hobbit actors were filmed first. The human-sized characters (Gandalf, Aragorn, Boromir and Legolas) were filmed in a second take, and the two shots were composited at different scales to make one image, making the initial Dwarf/Hobbit character shot seem smaller.
