Jack: I don't play a lot of convicts or mafia guys. I'm usually a professional, a doctor, lawyer, banker... that kind of thing. But sometimes you get to be the twisted guy, too, which is what I'm relishing so much about this [Heroes] role. There's nothing worse than playing a milquetoast. I'm happy to play a jerk, and I'm happy to play a bad guy. It really is fun to be able to play somebody who has a dark, sinister side.
