I never make a distinction between doing a film in Hollywood or doing a film independently. It's just the story. It's always the story for me. The constants are that it should challenge me and I shouldn't repeat myself. And the story should always be a story worth telling.

There's this thing that's come about that wasn't there when I started acting which is they do this thing called a chemistry test. They put a camera in front of two people, it's usually a boy and a girl, and they go, [whispering]. It's impossible. You can't manufacture it or film it, it just has to happen.

It was very much about performances, the whole ensemble thing was just great - everybody working together. Sometimes it didn't feel like a film set. It wasn't technically driven, it was very, very enjoyable

You're an actor who's Irish, not an Irish actor. And you shouldn't be limited by your extraction.

My wife can see always how a part affects me personally because she has to live with it.

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 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.
