I think acting is something that is within you. It's a very natural thing for me. It comes from myself, really.

What we do every St. Patty's day, which is wear green and drink a lot of Guinness. And maybe cry a little bit and laugh, and everyone will have to sing a song. That's how every funeral, christening, and wedding ends up in Ireland. Everyone ends up having to sing a song by the end of it.

I love a lot of comedy actors and actresses like Kristen Wiig and Tina Fey and all those women who are really brilliant and funny.

We've done a lot of films now about the IRA, we can move on from all that. I loved '71 because I think it showed a very honest trail and what it was actually like. It wasn't one-sided. I really respect ['71 director] Yann [Demange] for what he did. But we have done a lot of those things.

I've been dealing with so much press for Brooklyn, and now I am rehearsing for a play, and it is hard.

Acting is one of these things that I can't really describe - it's just like, why do you love your mum and dad? You know, you just do.

There's no one out there like Quentin Tarantino. His films have a signature look, and they never just stick to the same kind of story.
