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 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've had the pleasure and the great luck to work with some incredible actors over the years and you have to observe and learn and take something from it and try and become better yourself.

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

You know, I'm a skinny Irish guy.

But television affords you, what you just described, to - over the course of 18 hours, now that we're doing a third season - tell the story of this man. You're not under any obligation, really, to do massive expositional stuff at the beginning. You're at liberty to say, "Come with us on this journey," and, gradually, you become aware of what his motivations are, what drives him, what his weaknesses are, what his strengths are. That's what I think's sucking people into these worlds, because it is kind of like a novel, you just go really, really deep.

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.
