Mark Hamill, known as both Luke Skywalker and one of the most revered voices of the Joker, says he'll be hanging up his acid-squirting flower after completing Batman: Arkham Asylum 2. In an IGN interview, the veteran actor says he was reluctant to return to the role for the original Arkham, and even more so for its sequel. "This will be my last, there's no question about that," he said. "But it's the last hurrah."

Hamill says his original reluctance was due to feeling he had "left the role on a high note" after the cartoon series. "But they said, 'We got Paul Dini,' who was my favorite ever Joker writer, 'and Kevin Conroy,' who I love. This was a real reunion and a very pleasant experience. So of course I relented, but I had no idea it would have the impact it did." He says he was similarly hesitant to sign on for a second game, feeling they couldn't top the original. He changed his mind when Rocksteady told him what they had in mind for the character in the sequel. "But I'm sworn to secrecy!" he claims.

The finality of the statement has led to speculation that Joker will die in this sequel, which is supported by what we've seen. The teaser trailer showed a sickly Joker, giving a hacking cough between his cackles. We'll have to see how Rocksteady intends to make this his final joke.
