Because actually it's really hard to get things made. It takes years. To fight the fights you inevitably have to fight, even when you've produced Harry Potter, you'd better have the commitment and the passion to knock down walls, not take no for an answer.

I got a few things, because I think the props are so beautiful as much as anything else. The detail of the work is something that one has no idea of.

I don't think you can be a director without a kind of sense of competitiveness.

But there's something about the simplicity of Auschwitz... there's just nothing. There's just photographs, there's a room full of limbs, a room full of hair, and then you go into the place where the gas chambers were. You walk down these halls and the efficiency of it is so inhuman. The place is so powerful, just for its utter bald, bare simplicity.

All we try and do is make the best films we can. If you do that then hopefully the audiences will come, and they have. Everything else is gravy.

The most important thing is that you have to have the visual effects working for you, instead of you working for the visual effects.

Making the films is never easy, but actually that aspect of trying to make a better film or to keep the standard high is something that comes organically.
