When I was at school studying biology, I wanted to be a medical researcher. I did work experience at St Mary's Hospital in London, and I begged them to let me see the post mortems. So the first time I saw a naked male was at 15, when I saw an 89 year old man who had died of a brain hemorrhage.

I did a lot of serious plays, and I did the Oxford Review as well, which is supposed to be funny, but I'm not sure how funny we were when we did it. Then, when I finished my course, it was only then that I decided to go to drama school and try and do acting because I was enjoying it so much and so on.

I like people who don't accept boundaries. Like Florence Nightingale. And Napoleon or Louis XIV, though I'm not sure how much I'd have liked to meet them. I admire people who aren't circumscribed by circumstance.

Frankly, as much as I love to improvise, it hasn't been difficult to stick to the script on 'Mad Men.' The writing is so precise, and the story so carefully crafted, that I don't think there's room - or need - for ad libbing. I could never come up with dialogue as lovely as these writers do, anyway.

I saw someone the other day with yellow on their eyelids, and it looked so fresh. But I thought if I did that I'd look like a clown. So I went and I bought some yellow eye shadow from M.A.C. and I noticed that when you mix it with water it works better. So I tried it, and I looked like Big Bird. I will never do that again.
