There's always a level where you think you can improve and do better. Certainly at the beginning... I did four years of straight theater without ever having a part in a movie, and I remember being far more nervous on a film set than I was on the stage. It took a while for that to become less so.

I don't care if people perceive me as always selling out because I'm doing a studio picture. For me, the whole thing is you should be diverse in your choices; that's the beauty of being an actor, you should be able to do that.

I don't consider myself a shy person necessarily, but there's something about getting under the skin of a character and allowing you an abandon or a sense of courage that you would never have in your own life.

[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.

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 think if you play characters, it's very important not to ever tag them with any sort of disorder, or diagnose them, or whatever. You have to normalize the behavior to get inside the character.

All I've tried to do as an actor is follow the good writing. That's been my main drive. It's not always possible, so when you do come upon it, like when I came upon this, you realize pretty quickly this is something you need to be involved with.
