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.

The minute I get into a hotel room, I scatter my stuff everywhere. It's like a bomb site within a minute. So I suppose that means I'm trying to nest.

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.

I probably dreamt about running off to America or something when I was 16 because it just seemed like I was studying algebra and going, 'What am I going to use this for?

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

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.

It was my dream for years... to train. Dominic [Cooper] went and he's doing alright. But some people don't go and do brilliantly. Although I think there are things I missed from not having trained. I think I'd be more confident on stage had I gone because I think it means you're equipped with better vocal training and things like that.
