Your own barometer is all you have to go by, and often what makes a good director is knowing when not to say something. On occasions you can find yourself on a film set where the person who is wearing the director's hat is only trying to justify his position.

Being a good director is knowing sometimes when not to say something.

By the way, the Harry Potter series is literature, in spite of what some people might say. The way J.K. Rowling worked that world out is quite something.

I applaud anything that can take a kid away from a PlayStation or a Gameboy. That is a miracle in itself.

At 23 it was all about acting. Today it's getting my kids to school, making sure that they've done their homework. I'm in my fifties, and I'm turning into a square.

I like a cheese and pickle. Nice cheese and pickle on a real old-fashioned bread. Ploughman's lunch.

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.
