When you idolise someone, or you hold someone in such high regard, you just want them to be everything that you think there are - and when they are it's just lovely.

On film sets I can see everyone, and I really still find that so difficult.

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.

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 makes it easier, if you can't do an American accent. I don't know. It's different. I played a character in Never Let Me Go where the script for my character was very sparse, and I enjoyed it. With Never Let Me Go, I had a whole book written from my character's point of view, so I always knew where I was. But, with Ryan [Gosling], it was just easy. He's such a brilliant actor and he is so prepared. He doesn't have to warm himself up to be in a scene. He's just in it. It draws you in, in a way.

Remakes are a difficult thing 'cause some people feel very protective of the original.

I love New York - maybe more than Los Angeles or London. I think I'm happiest in New York.
