I've always been quite careful about what I wanted to do. I've just never wanted to revisit old ground or do something that's easy. I want to do something that I would look at and go, "I don't know what to do!" The most exciting thing is when you're a bit scared, so I'm looking to find something that's really terrifying.

I don't wear a bikini on the beach. I walk around my house in pyjamas. I haven't seen myself naked in the mirror for probably a decade. I'm very prudish.

There was an article in the New York Times that said that young men can't maintain healthy relationships because they're so influenced by pornography and what they see on the screen. It's something to be talked about.

In London, people can be so... well, it's not even a case of people being unkind or unfriendly. You just don't make any contact in London. You go from A to B with your eyes on the pavement.

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.

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.

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