I'm Irish and very proud of being Irish, but as an actor, your extraction should be secondary, really. You should be able to embody whatever character it is, wherever the character comes from. That's always been important, for me. I'm an actor who's Irish, not an Irish actor.

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

Actors' careers are random with a capital "R."

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.

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'm interested in pressure, I'm interested in duress. All the great works of art, or film or literature, in my opinion, have elements of those in them.
