I'd love to see Mark Hamill on this
Now there's a guy with alot of interesting things going on, and I don't mean the kind of E! *beep* with papparazi's in trees and people commenting on his shoes or whatever. He's a guy that's certainly been through the rough and yet is still going strong.
He was an iconic figure in the 80s who reinvented himself as an iconic voice actor. Most notably as the Joker from the Batman mythos. It's like Shatner going from Kirk to Denny. I think there's alot of history there that would be intriguing to hear if he'd be willing to share it.
