When I worked with Chevy Chase, Michael Ritchie would say, "Just ad lib and try to break me up. Just insult me. Anything." When we were doing his close-up, or when my back was to the camera, I would come up with jokes or quips or anything, to get a real reaction out of him. He was smart enough to know that was gold. So it was great fun working with him and Michael, and getting to see how the two worked together. I think Fletch and Clark Griswold were Chevy's two best roles. He's so incredibly talented and still vastly underused.

Working with Steven Spielberg, how bad could it be? But "1941" was one of those excessively big movies where every action scene was done and re-done and re-done again. It was so overproduced and overly expensive. And it wasn't terribly funny.

I grew up on a set. The guys I hung around with were crew guys: the camera department, the prop guys. I was like the third kid through the door when I was a kid actor on Leave It To Beaver. I was always one of five guys who would have a couple lines. I was a journeymen actor in my first career, so I was appreciative of the journeymen on the set.

The funny thing about The West Wing is - and I don't know what Aaron Sorkin says about it - but I'm convinced it was a comedy. It's a very intellectual and cerebral comedy, but it was SportsNight in the White House. It had an energy and a vitality and an intelligence and a passion that's rare. And it was extremely difficult to do, because they were so demanding about the dialogue.

I kept thinking that with all those first jobs, "This is the beginning of something!" And then nothing would happen. That's the real Hollywood.

I read Animal House and I said, "I will burn down a house to be in this. I have to be in this movie." I read 1941 and I went, "Well, if Steven Spielberg likes it..." But it just wasn't on the page. It was a very big, unwieldy thing, and there were so many characters. It was fun to shoot, but I didn't know what the core of it was.

As an actor and a director, I always let my actors go... assuming they have good ideas.
