So Harry Potter came in and it is nice that I have kids of the right age. I took them to London and they walked around the set and met Harry Potter and that is thrilling.

I have three kids who like Harry Potter so I was sort of aware of it. You can't really move from it: it's on buses, in stores, it's everywhere. One of my kids has read the books; the other two are too small but they like the movies.

Well, I needed the work - that's the honest answer. I haven't worked for a while, a couple of years. So I thought it would be nice to get back to work and earn some money.

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

I never told my father I loved him before he died, and I have a lot of issues about that. They're all swimming around in my head, in my heart, unresolved, and in a way it felt fitting to dedicate the film to him.

You always hope that the cloak of inspiration will fall, and you'll be O.K.
