Enter the Batcave!

The Dark Knight is a 2008 American superhero film based on the fictional DC Comics character Batman. The film is the sequel to the 2005 release Batman Begins, which rebooted the Batman franchise after an eight-year hiatus. Christopher Nolan, director of Batman Begins, continues as the director of the sequel, which stars Christian Bale again as Batman and Heath Ledger as the Joker. The film follows Batman becoming more of a detective, dealing with the escalated situation from the end of Batman Begins as well as the dilemma of his vigilante crusade, and his friendship with district attorney Harvey Dent, played by Aaron Eckhart.

Nolan was initially unsure of returning for the sequel, but eventually decided upon creating a new interpretation of the Joker, based on the villain's original appearances in comic book lore. The Dark Knight was filmed primarily in Chicago, as had been done for Batman Begins, as well as several other locations in and outside the United States. The director also used an IMAX camera to film four major action sequences, including the Joker's first appearance. The Batsuit was redesigned, with a cowl allowing Bale to move his head, and a recreation of the Batcycle known as the Batpod will be introduced.

The studio undertook a viral marketing campaign for The Dark Knight in which websites were created so Batman fan collaboration would reveal items such as new screenshots from the film. The film will also be marketed by selling related toys and an animated direct-to-DVD anthology titled Batman: Gotham Knight that is set between Batman Begins and The Dark Knight. The Dark Knight has a tentative release date of July 18, 2008 in the United States.
