It's quite interesting, looking back at the first one [film about Harry Potter], nobody knew whether or not it was going to be successful as a film. The books were of course already very successful, but that's happened before, where the books were successful and the films weren't at all. But it turned out that they were.

'The Elephant Man' was hugely enjoyable to do. I thought the one stage, when Chris Tucker did the first makeup and it took 12 hours, I thought they'd actually found a way for me not to enjoy filming.

It's quite a dangerous career move to go wilfully on making films that may not find a distributor.

Lotte Lenya was all emotion. She wasn't anything but emotion. She was not an intellectual.

I felt, you know, body and soul, as it were. But, of course, I mean, I - at that age, I didn't think in terms of being professional. I didn't know anything about it. That happened later.

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 don't like no confusion.
