Something like 'Alien,' that was not so easy. If there's any genre I wouldn't mind not having to do anymore, it would be science fiction. It's just all to do with the toys, and there's so much hanging around.

We are all racing towards death. No matter how many great, intellectual conclusions we draw during our lives, we know they're all only man-made, like God. I begin to wonder where it all leads. What can you do, except do what you can do as best you know how.

I'm not accustomed to doing films without seeing the script. There are certain people that are auteurs, and you accept them regardless of whether you see a script or not. But Spielberg is not an auteur.

I'm really the addition of other peoples' imagination, quite honestly. It's what they see me as, and I'm very happy to comply. I find things are more varied that way.

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 put everything I can into the mulberry of my mind and hope that it is going to ferment and make a decent wine. How that process happens, I'm sorry to tell you I can't describe.

I've spent a great deal of my life doing independent film, and that is partly because the subject matter interests me and partly because that is the basis of the film industry. That's where the film-makers come from, it's where they start and sometimes its where they should have stayed.
