I think I'd rather do [acting] in the real place. It requires different things, working with green screen, but its an imaginative exercise anyway, the whole business of acting, so it just gives you a bit more to feed the imagination. Unless it's really silly, just two of you stuck in a space with nothing but green screen that's got to be pretty difficult.

I'm very director oriented.

You have to learn to cut your cloth accordingly. But it seems to be a human weakness. Once you start making a lot of money, you just join in with everyone else. It's like the banks, and we've seen what happens there.

If I hadn't been a part of [Harry Potter] I would have been deeply upset.

I mark a script like an exam, and I try not to do anything under 50 per cent. Similarly with the part. And also film is a peculiar thing, parts don't necessarily read in script form anything like as well as they can do when it comes to materialising.

The great joke is that a realist is an optimistic pessimist. That's very witty. Whether it's truthful or not, that I don't know.

In the States it's more and more difficult to get an independent film off the ground, and you certainly wont get the opportunity to play something like that in a studio movie.
