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

It's always hard when you're playing someone for a lot of people out there who are going to see the movie after reading the books. There's a communion between a reader and the writer, so people will have an idea who Sirius Black is and I might not be everyone's idea of that.

How do you remember all those lines? By forgetting everything else.

People imagine that actors are being offered everything and you are not. So things come in and sometimes there are things that I want and can't get a meeting on, or go to a different actors.

Being an actor is a good way to earn a living. And to meet fabulous people. It's great to live very comfortably. I've been lucky, I've had a lot of fun with great roles, but it is true that if I were extremely rich, I would stop and I would go to play football on a beach in the Caribbean with my children.

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

'Nil By Mouth' was a bit autobiographical, but as I always pointed out at the time, that's not my dad.
