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 don't think they'd ever make a movie about Chuck Baker but I'd love to play Chuck Baker

[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'd probably have been wealthier if I had stayed with law, but pretty miserable doing it.

I started off in theater; I did exclusively theater for four or five years. In the last few years, television has come along but I can still make film. I feel very privileged that I can move between them.

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.

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.
