All of a sudden I was Joan [Mad Man] and they're going, "Oh, so she plays a badass in this." And I'm like, "Oh my god, I get to play badasses." Firefly was a little bit of that, but she started out as a mouse and then she turned into a dragon. But I never really had that opportunity. So all of a sudden people were like, "Oh, do you feel like you're being typecast?" I would say, "No, this is just opening the doors." No one thought I could do it and someone finally trusted me to do it.

If Mad Men had taken place in the '90s it would have been just as believable. But the fact is that was the perfect storm and with the fashion and the sets and the writing and the actors it just all made sense and it just was one of those things that you can't explain.

I love my body as it is. People in the industry have been telling me to lose weight for years but I like the way I look. I give credit to my mom for helping me feel good about my appearance - for making sure I never felt embarrassed about my body, because she was never worried about looking too big.

I think Joan's advice would be: always know more than anyone else, always be discreet as possible. And never cry at work.

I dyed my hair about 42 different colours, and kids can be pretty judgmental about people who are different. But instead of breaking down and conforming, I stood firm. That is also probably why I was unhappy.

Some of the things people have said about me, well, they're unbelievable

A woman is beautiful when she stands out as an individual—it's a woman who has her own style and the confidence to pull it off. Half the women on the streets in New York City achieve this. I get so inspired every time I'm there.
