Build a movie plot around this: Who is entered the castle? Sirius Black
Answer:
It opens at the Dursleys' home where Harry Potter (Daniel Radcliffe) lives and is staying, as usual, during the summer holidays. Uncle Vernon's (Richard Griffiths) sister Marge (Pam Ferris) comes to visit and treats Harry with general contempt. She viciously insults him and his parents, angering Harry who unwittingly uses his innate magical powers to cause her to inflate, and float off, out of the Dursleys' house and into the twilight. Harry flees the Dursleys' home, furious. At first he walks with determination but soon grinds to a stop as he realizes he hasn't anywhere to go. He sits down at the edge of the road with his trunk.

While there, Harry learns that Sirius Black (Gary Oldman), an alleged supporter of Lord Voldemort, the dark wizard, has escaped from Azkaban prison. Harry must meet the Minister of Magic Cornelius Fudge (Robert Hardy) and he fears expulsion from Hogwarts for his using of under-age magic out of school. However, the matter is surprisingly dropped as "...the Ministry doesn't send students to Azkaban for blowing up their aunts." While at The Leaky Cauldron Harry also reconvenes with his two best friends, Ron Weasley (Rupert Grint) and Hermione Granger (Emma Watson), and the rest of the Weasley family. Mr. Arthur Weasley (Mark Williams) pulls Harry to one side to warn him about Sirius Black. He suggests that Harry needs to be cautious of Sirius Black due to his allegiance with Voldemort. He believes that Harry is the only thing which stands in the way of Voldemort returning to power and that it is on this premise that Sirius Black has escaped from Azkaban.
