I suppose I've always been attracted to this sort of outsider in general - in literature, in music, politics, whatever - and to the person that is able to be relentlessly themselves. I don't think that I have that quality, that strength of mind.

I have a list as long as my arm but I find those lists sort of self-defeating because you start to name and then after [the interviewer] leaves the room you go 'Ah, I forgot this person or that person.' So I just don't do it anymore. Hopefully if you make work that people like, they'll get in contact with you.

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.

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 suppose I tend to like slightly darker things - people have levelled that on me before and I accept that because in my opinion, if I mention the best movies or the best books, there's always something that's involving slightly darker element of out psyche. I like seeing people under pressure. I like seeing what happens to people when they're under pressure.

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 kind of loath to pick one project over another or whatever. You go into every film sort of thinking it'll be your best work, and that's necessary. I think in this business, you really have to be forward-looking the whole time. I think nostalgia is sort of the death knell for any artist.
