In an interview with IGN UK, voice actor extraordinaire Mark Hamill -- also involved with something called Star Wars, we're told -- revealed that he won't be revisiting the role of Joker after the release of Batman: Arkham Asylum 2. According to Hamill, he was reticent to take up the mantle for the sequel, saying, "My answer to [developer Rocksteady] for the sequel was, 'Guys, we're never going to be able to top the original.'" He added that he had intended to leave the role on "a high note" with his work on the original Arkham Asylum.

However, once Rocksteady told Hamill of its intentions for the sequel -- swearing him to secrecy in the process -- he agreed to reprise the role, though he's adamant this will be the last time. "This will be my last, there's no question about that," said Hamill, "but it's the last hurrah." Whatever Rocksteady has planned, it was obviously enough to get Hamill back on board, and that's reason enough to be excited, right?
