Obviously, my life and my job in 2010 is very different from Peggy's experience in the 1960s. I exist in a world that enjoys more equality between men and women. But I don't take any of that into my performance. I just want to play the character as who she is as an individual - scene to scene.

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.

I wish I was super-serious, anguished. I see those actors, and I am like, 'Oh God, they are so cool, and they seem so interesting.' I don't take acting that seriously.
