[We were very lucky that Sean [ Ellis ] researched the film [Anthropoid ] for many years.] We sort of piggybacked on his knowledge, and he gave us a lot of materials, which we read. For me, the greatest resource was actually shooting the film in Prague.

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.

I really feel actors should try and do as much diverse work as possible to try and keep it interesting.

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.

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 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 will always love film, the romance of film, sitting in the darkened room with strangers and watching a story for two hours - that will always remain and never be eroded by television.
