In this adaptation of the third book in J.K. Rowling's best-selling series, Harry Potter (Danielle Radcliffe) and his best friends Hermoine (Emma Watson) and Ron (Rupert Grint), must face the dangerous convict Sirius Black (Gary Oldman), who has ties with their enemy Lord Voldemort. The spectacular fantasy-adventure action of the earlier movies (SORCERER'S STONE and CHAMBER OF SECRETS) is once again presented here, as Alfonso Cuaron lends his unique directorial style to recreating Rowling's magical story on celluloid. A scarier, darker story than the first two, this one concerns the mystery behind why Sirius Black is tracking Harry Potter. Slowly Harry and his friends unravel the clues, and learn secrets about Harry's parents that had all along been hidden from him. Meanwhile, because the deranged Sirius poses a threat to all students at Hogwarts, the school enlists a group of daunting black ghosts called Dementors to stand guard. These flying ghouls have a powerful effect on Harry and frighten him to his core. Yet even these chilling obstacles don't dampen the spirits of the youthful wizards, who meet Buckbeak--a giant flying hawk-horse creature, welcome a new dark arts teacher (David Thewlis) and a new divination teacher (Emma Thompson), and are still determined to beat the rival Slytherin team in Quidditch. HARRY POTTER AND THE PRISONER OF AZKABAN offers a visually stunning interpretation of the revered book, and will thrill viewers with its special effects, it's penetrating John Williams score, and its superb performances.
