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.

Anytime you have a female protagonist, it's going to turn into some feminist angle, and it's not a conscious thing on my part. It's only recently that that's been pointed out by the media . . . or pointed out by fans. I also find complicated, flawed characters interesting. What's the opposite? To play one-dimensional, boring failures?

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.

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.

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.

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.
