When you sit and watch the film with an audience, the focus groups and the cards and all of that is the less what you're worrying about. When you watch a film with an audience you see what is working and what's not working.

I used to be a die-hard defender of physical film, which I still am. I love shooting on physical film and I think it's great.

Normally, I tend to be a very binary filmmaker. You give me a problem and a destination and I say, "All right. If you want to get from here to here, there's a series of if/then's that will get you there. And if you have other stuff you want to do along the way, I'll give you all the if/then's that are caused by that."

I've looked at all of Hitler's speeches thinking that there's gotta be one where he's 'I'm Hitler!', but there weren't any. His speeches were all about hope and prosperity - he ran on a platform of peace and prosperity. Hitler speeches that makes him sound like a villain are pretty hard to find, he was very detached from what he was doing, he kept himself compartmentalised from it.

Directing has completely changed the way I write and watch films.

I love films like Deliverance where you can watch it over and over again and decode all of its many different meanings.

I was writing from the time I was 12 years old, but I originally wanted to be a novelist.
