I think actors have to have clear goals in term of fitness, I think it is very important. I did yoga very seriously and I think that is a wonderful exercise. I take tennis lessons, and I swim a lot.

We, Brits, need to be sort of loosened up. And there's some transfer overseas, I think the more American fare that comes to the U.K., the more cross-fertilization there is that's perhaps changing.

I think every physical program has to come from good nutrition.

And I like the look on people's faces when I say I'm doing this movie called Pride and Prejudice and they kind of smile, and then I say I'm in a movie called Doom and they kind of do a double take and try and put the two things together. And they never quite manage to.

Ive been doing Pride and Prejudice all summer, so suddenly the chance to be holed up with a bunch of marines is quite attractive, and probably a necessary dose of male energy.

As a woman, you feel that you shouldnt want to better yourself against others. Ambition has become such an ugly word, hasnt it?

I don't think RADA wanted me, actually. When I was at Oxford I had a boyfriend at Central [School of Speech and Drama] and it looked like the most fantastic life, but I think not going makes you more free. Nothing can teach you what it's like to work on a film set, and the best education there can be for an actor is to walk up the street and observe human nature.
