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!

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.

Steven's Spielberg is one of the most visually talented and character-oriented directors I've ever worked with. And I learn from him every time I watch one of his movies. Good or bad - and he has made some awful movies - they're never uninteresting. He's made four or five of the greatest movies of all time. Perfect movies, like E.T. or Schindler's List or Saving Private Ryan.

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."

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.

Funny is funny. You can be fooled by the eye, but if your performance is funny to the ear, it will be funny. I think it's that if you don't have the visual, you have to infuse the full personality into the voice.

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.
