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!

The Dain Curse [Tom Fink] was a great job. I was in New York, and I was young - I think I'm 28 years old in that - and I got to work with James Coburn and Jean Simmons and Jason Miller. Plus, it was a Dashiell Hammett story, and I had a great character. It was fantastic to shoot.

I've gotten such good feedback from that [re-team with Wil Wheaton for Big Bang Theory appearance], and I hardly did anything.

I have to say, though, that somebody pointed out to me on YouTube that Conan O'Brien was being interviewed, and he was talking about how, oddly enough, he went to see that movie [South Park: Bigger, Longer & Uncut ] in Hawaii with his girlfriend or wife or whoever, and he didn't even realize his character was in it. But there he was, and he said, "This voice comes out of me, and I'm thinking, 'That's not me! Who is that? That doesn't even sound like me!'

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."

I don't know you could do a whole film about Dr. Okun from Independence Day.

The character of Brent Spiner. We certainly collaborate on the concept of that, but he basically writes the script, then it's sort of a combination of his voice and my voice.
