My wife can see always how a part affects me personally because she has to live with it.

I'm definitely a frustrated musician, though it's more in terms of wishing I was a better guitar player and songwriter. But I've never regretted becoming an actor instead. I think it's been a more pure form of self-expression for me. I luckily found something that I could aspire to be good at, whereas I never... I think I'd never quite reach that level of artist that I enjoy in the music world.

At the moment I'm doing this space movie, so I'm obsessed with physics and space travel. I know three months down the line it's gone. Then I'll be able to superficially say stuff about space.

The medium is secondary to the stories.

There's this thing that's come about that wasn't there when I started acting which is they do this thing called a chemistry test. They put a camera in front of two people, it's usually a boy and a girl, and they go, [whispering]. It's impossible. You can't manufacture it or film it, it just has to happen.

I'm pretty adamant to do an American accent because you get it immediately.

It seemed to work on camera. And there's very few films - because you make a lot of films and you meet people and you work very intensely and intimately and then you're gone - but there's a few where you actually make friends, and this [The Fall] was one.
