You need to be as clean of a slate as you can be, as an actor. You have to try to be open to every experience.

You know, I'm a skinny Irish guy.

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.

Having started out in theatre, I feel an impulse to do it as much as I can

For me, drama is conflict.

It's a very organic kind of way that people are discovering it, by word of mouth, which I always think is the best way for things to grow. In terms of the affect it's been having on me, I don't even notice that. It's lovely to be able to talk about a piece of work that you're very proud of, that I think's a complex piece of work and not superficial and has depth to it.

I guess because theater's so ephemeral and it's gone. You make this nightly contract with the audience and you redraw that contract for the next night, whereas film and television, it's forever. I suppose it's always about adopting personas, never about being yourself. I think they call it a "shy man's revenge."
