Batman becomes more of a detective in The Dark Knight, as he deals with the escalation of the situation from the end of Batman Begins as personified by the Joker, portrayed by Heath Ledger. He also deals with the dilemma of his vigilante crusade, and his friendship with district attorney Harvey Dent, played by Aaron Eckhart.

An animated direct-to-DVD anthology titled Batman: Gotham Knight, which takes place between Batman Begins and The Dark Knight, will be in stores early July 2008. Batman: The Dark Knight will be released on July 18, 2008 in the U.S. and on July 25, 2008 in the U.K.
