With theatre especially, you don't want to do it unless you love it - there's no way you can pull it off, making people happy, making yourself happy for 12 weeks or whatever.

I remember in 'Pride and Prejudice' I had to do a scene where I broke down. And before we filmed I spent like three hours imagining my mum's funeral. Actually, she's very much alive, happy and healthy. It was really horrible.

There's always the things that you think are going to be tough. I've been nude once, and I was like, "Oh, that's going to be a nightmare," and actually that was fine.

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

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.

When I went to the Oscars - the only time I've ever been to the Oscars - a few years ago, I wore this Prada dress covered in cooking utensils. I got drunk at the end of the night and started ripping them off and giving them as presents to people, so that was fun. I'm pretty sure that was the point of it, that's how Miuccia meant for it to go I'm sure.

What doesn't draw you into a Coen Bros. movie. It's amazing. I can't believe it! They're the Coen Bros. It's ridiculous.
