It was quite instant that he wanted Harry's approval. Did you notice that? And the children sort of rescued him this time. It's a great turnabout. That's what happens as your children get older. They do things for you, and it's quite shocking when they do.

I love films where the world seems to be going a bit faster and everything's a bit brighter and more in focus.

It's hell with that big beard and stuff. That's the one bit I don't like. Either you take out at lunch or you don't eat. So I opted not to eat, 'cause having to put it on twice is horrific.

The interesting thing about Hain is that he's not a very interesting character. He's not fabulously clever. He's not a great policeman. He's not hugely charismatic.
