John Belushi infused Animal House with this spirit of guerilla filmmaking. John Landis came from that world too, and all the National Lampoon writers were from that world. It was just chaos on film. Controlled chaos, though. We stayed very close to the script. It was a very formal kind of movie, if you look at it. Formally photographed and structured, with certain elements of improv.

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'd been working on more traditional movie sets and TV shows at Universal. All of a sudden, here we're on location in Animal House, and it's down and dirty and quick. It was the way the new commercial world was shooting; the way the indie world was shooting. These were lighter, faster cameras. It was a generational change.

I'll never forget John Heard doing Shakespeare In The Park with Raul Julia and Richard Dreyfuss. It was 30 years ago, I guess. It was Othello, and John Heard played Cassio, and while everyone else was "Acting!" Heard came on talking normal, and everyone in the audience was leaning in to follow him. I wasn't doing that in Bus Stop. I think in that performance, I was putting it out a little too much.

The great thing about theater is the doing it again and again and again.

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 always wanted to be an actor. I was one of those lucky kids - or cursed kids - who always knew what he wanted to do. My wife too. She's a ballet dancer, and she's known what she wanted to do since she was 5. My mother used to tell this story about how our TV set had been taken to be repaired, and back then, they took the set out of the console. So there was this empty console with an empty TV screen in it, and I would climb inside and be like, "I'm on TV!"
