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.

I've never really felt like I was a child actor. Just an actor who happened to be quite young.

The written word can be powerful and beautiful - but films transport us to another place in a way that even the most evocative words never can.

I like my characters to be ones I think about long after I've finished reading the script.

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.

When I can't get the character out of my head, and I'm in my bedroom and I start to actually act out the scenes that I've read in a script, I think okay, I really want to do this.

I don't look at rushes, or I don't go to the dailies. I don't even really look at playback unless it's an action scene or a move that I need to do better, something like that.
