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

If I hadn't been a part of [Harry Potter] I would have been deeply upset.

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.

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.

Acting is an imaginative leap, really. And imaginations prosper in different circumstances. And it's being able - I can't tell you how one does, but one tries to read those circumstances correctly.

I think you can fan the flames, but I think in the same way that a mathematician is a mathematician - He's not taught to be a mathematician. He either has a feeling for equations and an understanding and delight in it, not only in the purity of it, but in its beauty as well.

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.
