I have no idea how much money I've got.

I'm never going to be in something as commercially successful as 'Harry Potter' ever again. It's impossible. So that gives me incredible freedom to go off and make the slightly off-the-wall films that I want to make.

In terms of drama school, what that will give you that you won't necessarily learn on a film set is the technical ability - ie, projecting your voice and stage craft.

I think I'm always very naïve. With 'Kill Your Darlings' and 'Horns', I'm like, "Why wouldn't everybody love this?" But I guess it's going to divide people in some ways. But if you're willing to go with it and suspend your disbelief, you're going to get something amazing and something unlike anything else.

Fans are really important for me. And if they take pains to write me, it's the minimum that I answer myself.

Religion leaves no room for human complexity.

You never want to be forced to do something. But the world around you starts to influence you in ways you never expected.
