No, they're not putting Heath Ledger's Joker in The Dark Knight Rises
Despite fervent Internet speculation to the contrary, Christopher Nolan is not a monster, and he will not be using a combination of leftover footage and CGI to force the late Heath Ledger to reprise his role as the Joker in The Dark Knight Rises. “I heard the rumor. We’re not doing that,” Nolan’s wife and producing partner Emma Thomas said when asked by The Hollywood Reporter. Nolan added that Ledger would most definitely not show up in the new film. As it turns out, the whole thing was simply a rare miss in the arena of unsubstantiated Batman rumors.
