Year Three. Convicted murderer Sirius Black has escaped Azkaban and is headed to Hogwarts to kill Harry. But Voldemort’s right hand man is the least of the boy wizard’s concerns as the school is plagued by Dementors, the black-hooded guards of Azkaban who force Harry into uncontrollable fainting spells. To fight these creatures, Harry takes special lessons from new Defense Against the Dark Arts teacher Remus Lupin who harbors a deep secret and his own connection to Sirius. Directed by Alfonso Cuarón, Prisoner of Azkaban is widely considered the best of the Harry Potteradaptations for striking a perfect balance between the complex and dark themes of the story with the fantastical elements. This is also thanks to stunning performances by Emma Thompson as Professor Trelawney, Michael Gambon as Dumbledore, David Thewlis as Remus, and Gary Oldman as Sirius.
