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!'

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.

It's funny that you can murder someone horribly and graphically and disturbingly in a horror film, and it's not an NC-17, but if you put a naked man on screen, everyone freaks out.

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.

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.

People always say, "You played such a strong character." I remember someone said that to me when I played a role in Shame, and she was a suicidal mess. I said, "She's not strong at all; she's incredibly weak." But "strong" to people means "real." It means you believe that's a person who exists, as opposed to some two-dimensional depiction of women.
