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 thought, well, you might see curves there, but that's just a bone - so even if I lose weight that's not going to change anything. That's how I look. That's my shape. Do the math.

As for the herbal cigarettes, for the most part I don't smoke as much as the guys do. I'm usually just strutting around a bit more so I don't actually have to be inhaling it. I'm lucky because I do have scenes where the cigarettes work beautifully to punctuate certain things I'm saying.

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've been telling everyone for weeks now about how I get to play Lois Lane. It's a big deal. There are a few characters throughout your life which everyone knows and this is one of them. I can't wait.

I'll always miss Mad Men, of course, but it is interesting to finally answer different questions after nine years. Not that that's a criticism to anyone, but just simply as a character for nine years, you're going to get a lot of the same questions for many, many, many years. This is sort of refreshing.

Even when I did Ryan Gosling's movie (Lost River), we had a very '80s kind of vibe and I would say for two or three months after that, I was dressing in a very sort of '80s way.
