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.

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.

Kurt Russell said another brilliant thing. He had starred in umpteen movies by that point. And he said, "Generally speaking, in every film I've done, there are only about three or four scenes that I can really do something with. For the rest of it, it's not so much that you don't have to prepare, but there's not much you can really do. You just do what is asked of you in those scenes. You don't want to do too much."

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!"

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.

Going through a divorce after twenty-five years of marriage was the most difficult time for me. It was challenging to reorient my life from being centered around family, a family home, and a long-term relationship.
