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.

Leonardo is the most incredible actor, on the planet, with a couple of people alongside him. Getting to act with him is just [amazing]. I walked away from my audition for that and I couldn't believe that I'd been acting with him. I've worked with amazing people, but my friends freak out that I'm working with him. I freak out in a geeky acting way. They freak out in a starstruck way. He's Leonardo DiCaprio, and his fame is so big. That's a complete tangent about that.

I did Wall Street, and then everything that happened with An Education took me up until March. I didn't want to work during that because there was just so much stuff. I didn't realize you had to go to so many parties. It was a nightmare! I had to go to all these parties! The glamour!

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.

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 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.

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.
