Each day, as you get older, there is a new perspective on life. It's a progression of some sort.

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.

Films don't take as long as people think. 'Harry Potter,' people always used to say, 'Well, my God, do you ever get any time to yourself?' I think I did, in 'Harry Potter,' over a 12 year period I did five days. So it's not exactly exhausting.

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.

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.

We shot ['Sailcloth'] five days down in Cornwall, and you couldn't have asked for a more beautiful place. It was a couple of tough days at sea, but when I say tough it was still enjoyable.

I find it difficult to say, like "which child do you prefer the most", and its a sort of surface choice. I've never known how to quite answer that one adequately.
