I'm, like, y'know, I didn't have a problem doing one scene in Dude, Where's My Car? I'm certainly not going to have a problem doing one scene in a [Martin] Scorsese movie!

There's such a grand fraternity of actors who've played the Joker, not the least of whom is Mark Hamill, who voiced it for so long and was so great. I did it one time and... I've gotten some feedback on it from people who've seen it and really enjoyed it, but I don't know.

Joey being one of my finest performances ever. Matt LeBlanc's basically doing the same thing right now, playing himself on Episodes. When I did Joey, I really leaned on them to make me the biggest ass they possibly could, because, frankly, everyone in their heart of hearts thinks of themselves that way. Or at least I do, anyway.

A couple of years ago, I went to see a production of Wicked in San Francisco with a friend of mine, one that Patty Duke was in, and he said, "Do you want to meet her?" And I said, "Yeah!" And I went backstage, and she walked out of her dressing room, looked at me, and said, "I know you." And I went, "Well, uh, yeah, I was in My Sweet Charlie." And she said, "Yeah! You were the guy in the car on the road!" And I was. It was amazing.

I had no idea I was part of what was going to be a big mega-hit. I thought I was doing a B sci-fi movie [Independence Day]. And, actually, it was Jeff Goldblum who looked at me one day and said, "You know, I think this is going to be really something." And I said, "Well, I hope you're right." And sure enough, it turned out to be.

We had lunch that day [with Chris Ellis], and I was talking about this idea. I toyed with it a little bit on Twitter in story form at one point. And he thought it was a great idea, and he thought, "Well, let's bring my friend Harry Hannigan in, who's a wonderful writer, and let's see if we can put something together."
