Filmmaker Chris Columbus will not direct Harry Potter and the Prisoner of Azkaban, the third film in the franchise. Columbus — who helmed Harry Potter and the Sorcerer's Stone and the upcoming Harry Potter and the Chamber of Secrets — reportedly is tired of living in England, where the films are shot. According to Variety, Warner Bros. is eyeing Alfonso Cuarón, the director of the sexually-charged indie hit Y Tu Mamá También, to replace him. If you've seen Mamá, you know what an odd choice that is.
