I've basically grown up with Harry Potter, as so many kids my age have. It's kind of a part of my life.

I grew up my whole life in Ireland and obviously sound very, very Irish. I feel like it's just one of those things that just charms the socks off of people.

I've found that I'd be the first one to cut lines.

I would never want to move to L.A.

I remember being on Atonement and it felt very right to be there. There was so much excitement every day. I remember very vividly how it felt to be a child on a film set, and that is actually really important to hold on to for as long as you continue to make films.

If you don't have eyebrows, you don't really have a face.

Once you move away from home, it's never quite the same again. You expect everything to be just as you left it, and it never is. It's almost the first step into adulthood, realising you've got to make your own way.
