Warner Bros. has announced its intentions to make a sequel, with most of the film's main cast, including Christian Bale, returning. This would make Christian Bale the first actor since Michael Keaton to play Batman more than once. Christopher Nolan was only signed to direct one film, but comments he's made in interviews suggest he'll return for the next film. He has not publicly stated, however, that he will return. Screenwriter David S. Goyer has publicly stated that he'll only return if Nolan does as well.

Goyer revealed in an interview that he and Nolan have devised a rough scenario for a trilogy, using the Joker as the antagonist in the second film and Two-Face in the third. The second film would introduce the character of Harvey Dent, and the Joker would get captured, go to trial, and scar Dent either near the end of the second film or at the beginning of the third film, turning him into Two-Face.

Like Begins, the sequel is rumoured to not be a strict adaptation of existing Batman source material, but rather will borrow elements from some of the series' more celebrated storylines. Among the books considered to be used as source material are Batman: The Killing Joke, as the Joker's origin story, as well as Batman: No Man's Land for the issue of "The Narrows," which, by the end of Begins, had been isolated from the rest of Gotham and overrun by the criminals of Arkham Asylum.
