When I am on set or rehearsing for the play, the only thing I can talk about is the work I'm doing. In that way, I home in on what I am doing at the time. So maybe I am a terrible multitasker.

I play basketball, I surf and swim and go to the cinema and listen to music and read. I like shopping.

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

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

I was 12 and I remember every­thing. I mean, I had done two films before that. The first was actually with Amy Heckerling. It was so brilliant to work with her on my first film. Atonement was the third one I'd done, and I remember how it felt to arrive on set every day. I remember how it felt to get my wig off at the end of the day. I remember how hot it was.

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.

I'm very much for strengthening our industry at home. It's great now there's a lot of work happening but I think with Irish film in particular, the views were starting to get a little stereotypical and we were pigeonholing ourselves a little bit. We needed to get out of that.
