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.
