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.

This whole theory of alienation that intellectuals have been passing on, really is just to stop a lot of ham acting. If you fill something with a proper emotion, it didn't worry him at all.

Once you've started to dig a hole, you can't get out of it.

I've never known what I've wanted to do. I've never planned anything in my life.

When you're really working well with a director then you can be as outrageous as you like and so can he. And there's no worry about it.

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.

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.
