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.

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 think every director has a different methodology.

[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'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.

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

The best roles you have to fight for. You have to really want to do it and you have to go after it.
