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.

The core of Animal House was about prejudice, about equality, and about inclusion/exclusion. It was about a group of people who were together and anything went. Anybody who wanted in could get it in. Then there was that other group that nobody could get in, unless they were white, and just alike. It was very representative of the culture in the '60s, '50s, and '40s in America.

There is something about the vocal quality of the actors who can really do it. Jim Burrows, the great sitcom director who directed Will & Grace and Cheers, when an actor comes in to audition for him, he never looks at them. He just listens. Because funny is funny. You can be fooled by the eye, but if your performance is funny to the ear, it will be funny.

I love JFK. My mother had been a worker on his campaign and adored him.

As a director, I know everybody's job, and I know how to do it. I can smell bullshit when someone's telling me it can't be done, because I've seen it done a hundred thousand times.

With comedy, you really want to work things out beforehand.

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.
