'Harry Potter and the Order of the Phoenix' (2007)

What happens: Fearing widespread panic, the Ministry of Magic publicly discredits Harry and downplays Voldemort's possible return. Harry butts heads with a new teacher who also works at the Ministry. He begins forming a secret ... more student army of supporters. In the climatic battle, Dumbledore and Voldemort go head to head. Dumbledore reveals that Harry's destiny is to kill Voldemort or be killed by Voldemort.

Despite being the longest book in the series, the fifth installment is a placeholder of a movie. It's all about preparing for war, although it is fun to watch Daniel Radcliffe and Imelda Staunton annoy each other. The Dumbledore/Voldemort battle was converted into 3-D for IMAX audiences, making this film one of the first blockbusters to revive the gimmick in hopes of boosting sales.
