We were able to shoot in a lot of the locations where the mission actually happened and these guys existed, so that was kind of very affecting. We had a Czech crew and a lot of Czech actors. There's a great deal of authenticity to the project [Anthropoid], and Sean [Ellis] was very anxious that that was the case from the beginning.

In terms of trying to improve as an actor, for me it's always important to return to the stage. After doing a piece of theater for a prolonged period, I can think I must have surely improved in some way as an actor - you must be fitter than you were prior to doing it. For me, theater is very, very important in keeping things fresh and dangerous.

I'm kind of loath to pick one project over another or whatever. You go into every film sort of thinking it'll be your best work, and that's necessary. I think in this business, you really have to be forward-looking the whole time. I think nostalgia is sort of the death knell for any artist.

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

I personally think if something's not a challenge there's no point doing it because you're not gonna learn much.

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 come from a long line of teachers. Not only did I not go into the family business; I had an aborted law career and I played in bands. 'Disco Pigs' was my first professional acting experience.
