It's dangerous talking about yourself too much because you find yourself talking in sound bites.

I think we probably will end up in America because he would be giving up much more to come and live here. If you want to work in film, that's really where you have to be. But I'm not sure that being an ex-pat is very good for one's sense of self.

I had friends at school, but I was never part of a gang and I dreamed of that sense of belonging to a group. You know, where people would call me 'Em' and shout across the bar, 'Em, what are you drinking?' after the show.

Normal people, who can be good people but do bad things, are very interesting to me, and people that never get a parking ticket or never do a bad thing in their lives can be really dangerous.

It's more enjoyable when I'm disguised in some way; stepping into someone else's shoes is part of the reason why I became an actor.
