I think there's such a thing as a performance gene. If it's in your DNA it needs to come out. For me, it originally came out through music, then segued into acting and came out through there. I always needed to get up and perform.

There's a lot of comedy in Intermission but it's got this depth. It's not comedy for comedy's sake - it's informed by something else. I like stuff like that

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.

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

Then, at age 20, I discovered theater sort of by accident. Quite quickly, theater became more important to me than music. I began to realize that maybe my talents as a musician were quite limited, or had a ceiling to them, whereas acting seemed to sort of stretch before me. I got very passionate about it very quickly.

I don't know if anyone will ever sit beside me on a plane again.

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.
