Mark Hamill Is The Joker In Batman: Arkham Asylum
Mark Hamill has signed on to voice The Joker in Eidos and Warner Bros' video game Batman: Arkham Asylum. Hamill, who played Luke Skywalker in the Star Wars films, provided the voice to the sadistic clown in the 1990's Batman and Superman animated television shows, and more recently in Justice League. Fanboy favorite Kevin Conroy has also returned to voice the caped crusader. I'll take Conroy's Batman voice over Bale's Clint Eastwood imitation any-day.
