You have formal rehearsal, a lot of things you don't have in movies - which is, you have to formally rehearse. You have to know your back story, discuss it, and almost everybody onstage has to know each other's [story], so that when it comes time to actually do it, you can throw it all away. That's the way I like to - and I didn't realize until very recently - that's the way I like to prepare for movies.

I have a mentor. I have... guides. I have a lot of guides. Not a lot, but people whose opinions I really respect and who I will turn to.

It's daunting trying to do any service as an American to such a beautiful, fluid speech pattern that you [British] all have. We are just barbarians in comparison.

When I look at that now, all I think about is what a master [David Fincher] I was working with, and all of the things I could have watched and learned - and I didn't. And how, now, in my career, how I would love to have a ton of takes.

When I was 19, I thought [Brokeback Mountain] was going to be the best movie ever made. And everyone was going to see it and it was just going to be incredible. And then nobody saw it and it didn't get bought at Sundance. And it was a really great experience. Humbling. And then it's since found its way.

I think I'm generally - fear, fear is very still, so in terms of that kind of fear - there's so many different kinds of fear, but fear is something, particularly in movies, that's interesting, because it's created by the film maker, that was created by David Fincher, that's why he's brilliant.

When I was young, before school, my father would wake me up and we would go running together. A love of being physical, being active and being outside was something he instilled in me.
