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.

Twitter scares me. I think it's so amazing, like the internet in general, because of the connection that it gives people. But the concept that one 140-word post can change someone's life . . . that scares me. You can literally ruin someone's life with one tweet. So I only do Instagram. I love photography . . . and interacting with the fans. I do love hearing from them. I try to answer questions if I can.

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.

I love working with male actors, and I think there's a tendency to write really interesting characters that would work solely alongside men where they would be in a man's world and have to deal with that, and it creates a lot of interesting storylines. For me, it's kind of circumstantial, but I definitely enjoy it.

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

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.

If I'm not like my characters, I think just it's like a musician liking to play certain pieces of music rather than others. I just have more satisfaction when playing complicated things rather than some of your more straightforward, simple moments. . . . I like to be challenged.
