Fans rejoice! Mark Hamill will indeed provide the voice for The Joker in DC's animated take on Alan Moore's The Killing Joke, which is due out next year. The Star Wars: The Force Awakens actor had already expressed interest in reprising the iconic role for the movie, but sources have confirmed to Collider that it's definitely going to happen - in fact, word is he's already recorded his voice acting!
Mark Hamill has voiced the character on many different occasions, from Batman: The Animated Series, to the likes of Batman: Mask of the Phantasm, The New Batman Adventures, Batman Beyond: Return of the Joker, Birds of Prey, and more recently the Arkham Asylum video games. Alan Moore's graphic novel is widely considered to be the definitive Joker story, so it's great to hear that Hamill will be back. Now, fingers crossed that Kevin Conroy will also return as Batman!
