In the business of acting, those are the actors that make the trains run on time, you know? There's nothing without them.

I don't look back with any bitterness, though there are a couple of judgment calls and some '80s hairdos that I'd like to do over.

[On "John F. Kennedy" set] everybody was very interested in the accent. Even my collaborators were very curious to know if I was even going to do it. And I was, like, "You just can't not do it." I think everybody was worried that it was going to sound like the guy from... is it The Simpsons?

When I was young and crazy, I was young and crazy. It can be hard enough just to BE in your teens and 20s. Then add fame, money, access, and every single person telling you that you're the greatest person who ever was, and it can be a recipe for disaster. Some people literally don't survive it.

The fact is, I have a great home and I like to have people come up. I meet enough people just doing my grocery shopping; I don't need to go out and meet any more people.

There are so many family dinners you can do. I eventually had to go to them and say, 'Look, I don't do spatula work. I don't do scenes with oven mitts. If you're looking for that, you've got the wrong guy. I'm not doing scenes about casseroles. It's not happening.

Actually, if I had to do it over [leaving the show the West Wing], I'd do the same thing, because lost in the shuffle of it is that Aaron [Sorkin] left the same year I did. And I would not have wanted to be on The West Wing with somebody else writing it.
