Claims his inspiration for his own interpretation of the Joker's voice came from a mixture of Hannibal Lecter and Jerry Lewis. He portrayed the infamous Flash villain, The Trickster aka James Jesse (a word play for old west bandit Jesse James, a popular stunt for "Flash" creator Gardner Fox and other series writers), in both the short lived live action CBS series "The Flash" (1990), in 1991 (two episodes), and in the "Justice League" (2001) animated series in 2005, in the episode "Flash and Substance". He later went on to do a similar role as an animation voice-over actor... as The Joker. Is one quarter Swedish.
Mark Hamill Quotes (When asked by Kevin Smith on "Dinner for Five" if he's tired of talking about "Star Wars"): "To be honest with you, sure. I'm human. I mean, I like ice cream, but I don't eat it three times a day. And I've forgotten a lot of it. If I was still working on it, it might be different, but I've put it in perspective. I want to be supportive without being critical, but it's not mine anymore." "I think theater has given me the opportunity to show what a character actor I can be."
