You look at that movie [Dude, Where's My Car?] now, and you know exactly when it was made. And that's what kids were like then.

Of course, when you see [ musical numbers] in the movie [Out To Sea ], it's cut into a lot with other scenes, but we shot the number straight through, so here I am doing it, and sitting right in front of me in the audience was Donald O'Connor. And I was, like, "Oh, my God, I can't believe I'm performing a musical number in front of Donald O'Connor," who's one of the greats of the silver screen. But it was a thrilling experience, it really was.

Both of the Quaid brothers, Randy and Dennis, were in my class, and Tommy Schlamme, who produced and directed The West Wing with Aaron Sorkin, among many others. Marianne Williamson, who did A Course In Miracles, she was in my high-school drama class, too. So it was kind of an amazing class.

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.

[Fan In Lobby from Stardust Memories] that was just after The Dain Curse. My other big uncredited role from back then.

[The Aviator] came about through John Logan, who I've been friends with for many years.

I think it was somewhere around age 3 when I fell down the stairs at my house, and I got up and did a Jerry Lewis impression and got a big laugh. And I thought, "Oooh, I like that. I think I need to do this for a living!"
