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 like the little bit of distance that London affords me and I like living in a world capital. I like having the culture at my fingertips.

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 don't care if people perceive me as always selling out because I'm doing a studio picture. For me, the whole thing is you should be diverse in your choices; that's the beauty of being an actor, you should be able to do that.

You do your due diligence, you read as much as you can, and then, ultimately, I find that you discard that and you concentrate on the characters [of 'Antropoid'] and you can draw on [the research] if you wish, but I think ultimately it's about bringing as much truth and honesty to the portrayal as possible.

It's a very organic kind of way that people are discovering it, by word of mouth, which I always think is the best way for things to grow. In terms of the affect it's been having on me, I don't even notice that. It's lovely to be able to talk about a piece of work that you're very proud of, that I think's a complex piece of work and not superficial and has depth to it.

I think every director has a different methodology.
