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 want to be in 'Glee,' but I'm told I'm not famous enough to be a cameo yet.

I'd like to do a play, but I can't find the right thing. I don't want it to be a starring role. I just want to play a really interesting character.

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 did The Seagull, the Chekhov play, on Broadway, a couple of years ago, and I had done it in London, and I became completely obsessed with the character, Nina, that I played in that. She's an actress. I couldn't find a play after that, that I wanted to do, because I couldn't think of doing anything else. Every part is a disappointment, once you've done that part.

Posing on the red carpet feels like you're selling something that has nothing to do with you. If you do it with someone else, it's like we're saying, 'Oh! We come as a pair! Would you like to buy both of us? We're available for weddings and Bar Mitzvahs!'

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.
