I'm a champion napper. For the past decade, I've taken a nap at lunch on set. I have a noise machine app on my phone, headphones - and that's key. That's probably the most important thing. If I can get an eye mask on, that's great. And that's it. After a half an hour, I'm like a new person. It's just in that first half an hour, don't talk to me.

To go from Girl, Interrupted, where I had to cry every day, to a TV show like West Wing where I get to laugh and joke around every day, has been a welcome relief.

Looking back, I feel like I was really young, and at the time I didn't think that I was that young. It was extremely traumatic and awful and horrible. At the same time, it turned out for the best. I'm glad that I'm not there. I'm glad that it didn't happen when I was 50. I'm glad I didn't have kids. And I got that out of the way. Hopefully. Like, that's probably not going to happen again.

Even though I'm an actor, even though I know a little bit about film, I very much view things as an audience member. For me, whether it's TV, film, theater, whatever, it's a big movie, a small movie, whatever it is, I look for the truth in it. I look for the honesty. I just look for if it feels honest and real to me.

I don't think any of us could have possibly anticipated how successful Mad Men has been. When we were working on the pilot, we loved it. We thought it was special. We hoped and prayed it'd be a success. But, we didn't count on it.

One day you're there and then all of a sudden, there's less of you. And you wonder where that part went. If it's living somewhere outside of you. And you keep thinking maybe you'll get it back. And then you realize it's just gone.

I love baseball games. I got to go to World Series last year. I watch almost every Cubs game. If I can't watch, I get the updates on my phone. I don't like to go to parties that much. I don't like a lot of people around me, but not in like a weird anxiety way. I just don't like to have to talk to a lot of people.
