The first film is everything you want to say and how you want to say it. Lots of directors will do that and do it really well, but the second film is not so easy.

I find myself more interested in producing. Not because I'm interested in the financial side of it, but just getting together the right elements to make a film, that side of production. I would not be good on the financial side. It would be a disaster from the beginning.

Some directors involve waiting, and if you want to work with that particular director you're going to have to hang around.

If you do an interview in 1960, something it's bound to change by the year 2000. And if it doesn't, then there's something drastically wrong.

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.

By the time I came to do the final ones [Harry Potter's film], I was working on something that was massively successful. There was a huge difference in indulgence and all sorts of stuff. A very big difference in peoples' attitudes. They were very pleased with themselves. In human terms, it was quite interesting to see the difference.

I have lots of favourite memories but I can't say that I have a favourite film.
