If I'm in theatre, cinema doesn't even cross my mind. Similarly when I'm making a film, theatre doesn't cross my mind.

I never quite understand why we watch the news. There doesn't really seem much point watching somebody tell you what the news is when you could quite easily listen to it on the radio...

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.

I turn up in Los Angeles every now and then, so I can get some big money films in order to finance my smaller money films.

I am really the victim of other people's imagination.

I am not an enormous believer in research being the be-all and end-all. I get suspicious when I read about actors spending six months in a clinic, say, in order to play someone who is sick.

You can see areas where maybe you got a bit lazy, perhaps, or you see when you were really on form. I think an actor is very like a sportsman in that respect. You have periods where you're in terrific form.
