If you aren't already swept up in the book-turned-film craze created by Rowling, this film might just do it. Harry (Radcliffe) and his trusty pals Ron (Grint) and Hermione (Watson), now teens in their fourth year at Hogwarts, battle the forces of evil that swirl around Harry's mysterious past. Lord Voldemort makes a showing, and new character Mad Eye Moody (Gleeson) joins forces with the good guys to help Harry compete in the frightening and dangerous Tri-Wizard Tournament. Special effects are even better than the previous three films--old fans won't be disappointed; new fans will want to play catch-up.
