Getting sober was one of the three pivotal events in my life, along with becoming an actor and having a child. Of the three, finding my sobriety was the hardest thing.

I had a guitar when I was 6 or 7, a plastic guitar with the Beatles' faces on it. It would be a collector's item now. It would fetch a hefty sum, I imagine.

Rather like Batman, I embody the themes of the movie which are the values of family, courage and compassion and a sense of right and wrong, good and bad and justice.

One of my career ambitions was fulfilled working with John [Hurt]. I loved his work long before I ever had the idea of being an actor, so I was nervous to meet him. I was like a fanboy, like that annoying character on 'Saturday Night Live'. I'm sitting there. 'Do you remember when you were in 'Midnight Express'? Remember that scene you were in?' And he doesn't disappoint.

I'm almost incapable of lying. I'd be a terrible spy.

People have an idea that one is in control of a career, a lot more than you really are. You can engineer things to an extent. But you are at the mercy of what comes in across the desk.

And costume is so important for an actor. It absolutely helps to get into character; it's the closest thing to you, it touches you. Some actors like to go into make-up and then put their clothes on, but I like to dress first; that's my routine.
