“Something wicked this way comes.” Harry (Daniel Radcliffe) returns for his third year at Hogwarts School, where escaped prisoner Sirius Black (Gary Oldman) is on the loose. Black is said to be after Harry, and complicating the situation is the presence of terrifying soul-eating creatures called dementors. To solve the mystery Harry and his friends employ a magical “Marauder's Map” of Hogwarts. (“I solemnly swear that I am up to no good.”) Directed by Steve Kloves; Starring Daniel Radcliffe, Emma Watson, Rupert Grint, David Thewlis, Gary Oldman, Alan Rickman, Maggie Smith.
