I'm always aware of the camera and it feels like that's the audience.

There's, like, marks next to an actor's name or something, and boy does that go up and down! Somewhere in there, which always causes my mate Miss Ruby Wax great hilarity, I was offered a biopic of Frank Sinatra. Even I knew that was a bad idea! They'll throw anything at you at certain times.

I never talk about 'Harry Potter' because I think that would rob children of something that's private to them. I think too many things get explained, so I hate talking about it.

I think the thing about film is, as it gets proved by a lot of young filmmakers now, that the medium will just go on reinventing itself, and so you just hope to be a part of that and not a part of some kind of endless regurgitation or 'Here I am doing what you know I do' kind of thing.
