If you behave like a celebrity, then people will treat you like a celebrity, and if you don't, they won't. There's not much to write about me in the tabloids.

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

I've always felt kind of safe on stage, protected. I've talked to other performers about this and they feel the same things, particularly in the live arena. I never get nervous going on stage to do a play. Doing film or television I'll have more butterflies.

But television affords you, what you just described, to - over the course of 18 hours, now that we're doing a third season - tell the story of this man. You're not under any obligation, really, to do massive expositional stuff at the beginning. You're at liberty to say, "Come with us on this journey," and, gradually, you become aware of what his motivations are, what drives him, what his weaknesses are, what his strengths are. That's what I think's sucking people into these worlds, because it is kind of like a novel, you just go really, really deep.

It's obvious that if you're going to play a character you need to amass information about that person and about their environment or their era that they're in and use as little or as much as necessary

[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'm definitely a frustrated musician, though it's more in terms of wishing I was a better guitar player and songwriter. But I've never regretted becoming an actor instead. I think it's been a more pure form of self-expression for me. I luckily found something that I could aspire to be good at, whereas I never... I think I'd never quite reach that level of artist that I enjoy in the music world.
