I don't feel I was ever a 'famous' child actor. I was just a working actor who happened to be a kid. I was never really in a hit show until I was a teenager with West Wing playing First Daughter Zoey Bartlet. In a way, that was my saving grace - not being a star on a hit show. It kept me working and kept me grounded.

At 15, you have to decide if you're going to go into professional dancing and really pursue it. I just a) knew that I couldn't stop acting, and b) I had that sort of foresight to understand that when I was 35 - if I was lucky and if I hadn't gotten injured - my career would be on its way to ending. Now, at 34, I really understand that. But at 15, I understood that as well. I was like, "I can't. That's just too risky.".

There's nothing like getting yourself into character and seeing a different person. It really wears on your vanity.

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.

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 think one of my biggest influences is Bette Davis. I've seen almost every one of her films, and she's been very inspiring to me.

When you audition for things, there's pressure to go in there with a complete performance, and it's kind of unfair because, if you get it, you'll have rehearsal and talk about it, and you'll have plenty of time with the script. So, for me, I really do feel like an audition is a sketch of what you might do.
