Being movie director you've got the art department, you've got the actors, you've got the camera department, you've got make-up and hair, and props. You've got your finger in all these pies, and you're making sure that everything cooks at the right temperature.

Nowadays, especially in big commercial films it's much easier for the audience, and they tend to get spoonfed. It's much more interesting to me, people leave the theater and they start asking themselves questions and find their own moral compass about what these characters have been doing.

Why not provoke some thought and get people talking about things? I like characters that are flawed because we all are. When people break up in a script, you think, Oh, right, there must be tears shed here. But maybe the fact of the matter is that they're both laughing.

We moved to Ireland when I was two and we settled in Killarney, Co Kerry. Where we were living in Germany is very industrial and very grey and my parents wanted to have countryside around for my sister and I to grow up in.

At one point you think, well, it's funny, I could just be a starving actor... So if somebody were to pull the plug right now, there'd be no room for complaint.

Even if I'm playing a superhero, it has to be steeped in reality.

Trying to identify and understand, as opposed to judging, is very important for me, in approaching characters.
