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.

I think there's such a thing as a performance gene. If it's in your DNA it needs to come out. For me, it originally came out through music, then segued into acting and came out through there. I always needed to get up and perform.

Every Irish person of my generation and earlier, we were raised Catholic and we'd have to learn it in school, we'd to learn the catechism by rote.

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.

I'm definitely a frustrated musician, though it's more in terms of wishing I was a better guitar player and songwriter. But I've never regretted becoming an actor instead. I think it's been a more pure form of self-expression for me. I luckily found something that I could aspire to be good at, whereas I never... I think I'd never quite reach that level of artist that I enjoy in the music world.

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

I loved The Fall; I was kind of obsessed with that show.
