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

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.

You know, I'm a skinny Irish guy.

I try not to think retrospectively. It's important, as an artist, to look forward, always. I do try to take work that involves some challenge. If you approach a piece of work and you're going, "Yeah, yeah, I can do that," then that's kind of a red flag.

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.

I was obsessed with Batman as a kid. I did the film in part just to be near the Batmobile. But I also think [director] Christopher Nolan made a very fine, intelligent film.

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.
