I didn't work for a year after Wall Street. I finished that in November, and then it was the following October that I did Drive, so I took a year off. I didn't do anything at all, really. I just hung around.

I'm not great at having my picture taken and I don't enjoy that side of it very much but I enjoy being with my friends and it's nice to have a reunion.

My agent in London told me, after Never Let Me Go, because I loved doing that so much, "If you're on a lucky streak and you're doing well, you should only take a part, if you can't bear the idea of anyone else doing it." That's been the case since then, with Drive and Shame and the play (The Seagull), and the stuff that's going on, like Gatsby. I would have been devastated, if I hadn't gotten those jobs.

I'd love to do a Paul Greengrass movie, or something like that, that's a character-driven action film. I'd like someone to make me go to the gym every day, and all that stuff. I don't know. Wherever the good characters are, I tend to try to get a job. It was nice because this was dipping my toe in the action genre. Maybe I might put my foot in, next time.

When you do bigger jobs there's more attention and when you film in New York you get loads of paparazzi everywhere. It affects your work because you're trying to think about the person you're acting with and you've got 20 other lenses taking pictures of you at the same time, and it throws you.

The thinnest I've ever been was after I had my appendix out, during the London run of The Seagull. I went down to 112 pounds and realized my brain doesn't work when I'm that thin, so I can't do my job. That's why, when I came out here, I never had that whole Hollywood pressure thing. I never said I wanted to be a lead actress; I never said I wanted to be a film actress. This need to trump everyone bewilders me. I'm only 25. I'm not better than anyone. I just want to watch other people and learn to be good.

I didn't want to do a costume drama. It's a great thing to do, but I've done them, and I didn't want to do the same thing again. Of course, costume dramas can be from all different eras, but at the time, I just felt very sure that I didn't want to be boxed in as an English actress. I wanted to be an actress, rather than an English actress.
