I've spent a great deal of my life doing independent film, and that is partly because the subject matter interests me and partly because that is the basis of the film industry. That's where the film-makers come from, it's where they start and sometimes its where they should have stayed.

I'm very director oriented.

I remember once when I told Lindsay Anderson at a party that acting was just a sophisticated way of playing cowboys and Indians he almost had a fit.

I think particularly Daniel [Radcliffe], he knows what he's doing. I'm sure he'll finish up a producer. He really realized what it was, knew the size of it. And it was gigantic, the biggest franchise [Harry Potter] in history.

I find myself more interested in producing. Not because I'm interested in the financial side of it, but just getting together the right elements to make a film, that side of production. I would not be good on the financial side. It would be a disaster from the beginning.

I stopped asking a long time ago, "why would you want me to play that?" I'm an actor. That's what I do.

A mathematician 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. I don't think that's something that you learn at school. I think you can get better in mathematics on a school level, but when you're talking about being a mathematician, I think that's definitely a gift of genes or whatever, you know? Whatever your pool is.
