I was trying to find ways of not being pigeon-holed like that. I didn't want to be tied down by my accent. I wanted to play Americans. I don't want to ever be doing the same thing twice, and I just didn't want to repeat myself.

I can actually cook one meal now, as opposed to before, when I could cook nothing. My family are very excited.

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.

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

I never sit in a cinema and go, "Ah! I want to be in that film!"

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 didn't want to do a costume drama. It's a great thing to do, but I've done them, and I didn't want to do the same thing again. Of course, costume dramas can be from all different eras, but at the time, I just felt very sure that I didn't want to be boxed in as an English actress. I wanted to be an actress, rather than an English actress.
