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

I did find New Zealand similar to Ireland. The people, obviously. I found that, ironically, although these two countries were very far away from each other, their humor was so similar and their outlook on things was quite similar as well.

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.

My whole life I try to make into a comedy, so it would be nice to see that onscreen.

I would never want to move to L.A.

When I was younger, I would mess about and have a laugh with everyone. I was doing Atonement when I was about 12, and as we went to do this very serious scene, the director Joe [Wright] came up to me ... I'd been giggling right up to the beginning of the take. And he came up to me and said, "Okay, you need to be serious now." I completely idolized him.

I certainly don't feel like I am desperate to run away from a film set. I love the hustle and bustle. Everything is sort of mad right before a take, and then it just settles, and you've got these two minutes of a bit of magic. I just love that in film.
