From a very young age I had an ambition to be a musician, and to do that professionally. That's what I pursued until I was about 20, playing in bands that were taken pretty seriously at that stage.

I'd love to work in America, some of my favourite films come from America.

I suppose I tend to like slightly darker things - people have levelled that on me before and I accept that because in my opinion, if I mention the best movies or the best books, there's always something that's involving slightly darker element of out psyche. I like seeing people under pressure. I like seeing what happens to people when they're under pressure.

I've had the pleasure and the great luck to work with some incredible actors over the years and you have to observe and learn and take something from it and try and become better yourself.

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.

I feel very lucky to be making good work still. The confidence of youth, or that sort of competitiveness you get when you're 22 or 23, the impatience - that's probably been tempered. Hopefully I'm slightly better company.

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.
