I did Wall Street, and then everything that happened with An Education took me up until March. I didn't want to work during that because there was just so much stuff. I didn't realize you had to go to so many parties. It was a nightmare! I had to go to all these parties! The glamour!

Leonardo is the most incredible actor, on the planet, with a couple of people alongside him. Getting to act with him is just [amazing]. I walked away from my audition for that and I couldn't believe that I'd been acting with him. I've worked with amazing people, but my friends freak out that I'm working with him. I freak out in a geeky acting way. They freak out in a starstruck way. He's Leonardo DiCaprio, and his fame is so big. That's a complete tangent about that.

I have always hated nightclubs, and don't like loud music.

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.

People get married when they're 18 and spend their whole lives together. I think their greatest fear is that someone will see it as a fling because they were young and it didn't mean anything.

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.

I've always played characters that were younger than myself.
