I learned a hell of a lot from my co-star, Kurt Russell. He's one of my closest friends and was one of my best teachers. He was the pro. He approached it like a baseball player. Acting is a contact sport to him.

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

I love John F. Kennedy. My mother had been a worker on his campaign and adored him. I was just a kid when he was around. I did a lot of preparation, a lot of research. I can't do him... I sort of get a slight Boston accent, and I tried to get his rhythm. My only fear was that I was too old to play him, because I was much older than he was when he died, so I was concerned about that. But it was one of those, "Oh what the hell, I'm doing this. It's a great part, and I'm going for it."

I am pretty relentless about exercise. I love working out and doing cardiovascular workouts. I'm now doing the Whole Life Challenge to discover the unhealthy patterns in my diet and to adjust them to more reasonable levels. And more yoga!

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

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.

Chevy Chase had been a bad boy with a drug problem, and had never really realized his potential. Fletch was the first movie he sort of straightened up on. And Michael Ritchie was Harvard-educated, 6'6", a brilliant director and political thinker. He was the guy the studio thought could handle Chevy, and keep him in check. And he could.
