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.

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 think my guideline has been to find things that inspire me. And as long as I stick to that, I don't think I'll have any problems crossing over to becoming an adult actress.

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.

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.".

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.

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?
