What I try to do is write from the inside out. I really try to jump into the world of the film and the characters, try to imagine myself in that world rather than imagining it as a film I'm watching onscreen. Sometimes, that means I'm discovering things the way the audience will, with character and story.

One of the things you do as a writer and as a filmmaker is grasp for resonant symbols and imagery without necessarily fully understanding it yourself.

The thing you fail to grasp is that people are not basically good. We are basically selfish. We shove and clamour and cry for adoration, and beat down everyone else to get it. Life is a competition of prattling peacocks enraptured in inane mating rituals. But for all our effacing and self-importance, we are all slaves to what we fear most. You have so very much to learn. Here. Let me teach you.

Films are subjective - what you like, what you don't like. But the thing for me that is absolutely unifying is the idea that every time I go to the cinema and pay my money and sit down and watch a film go up on-screen, I want to feel that the people who made that film think it's the best movie in the world, that they poured everything into it and they really love it. Whether or not I agree with what they've done, I want that effort there - I want that sincerity. And when you don't feel it, that's the only time I feel like I'm wasting my time at the movies.

As soon as television became the only secondary way in which films were watched, films had to adhere to a pretty linear system, whereby you can drift off for ten minutes and go and answer the phone and not really lose your place.

I have always been a huge fan of Ridley Scott and certainly when I was a kid. 'Alien,' 'Blade Runner' just blew me away because they created these extraordinary worlds that were just completely immersive. I was also an enormous Stanley Kubrick fan for similar reasons.

You never quite know what you're going to come back to and figure out how to make it work. You never quite know where that desire to finish something, or return to something in a fresh way, is going to come from. Every time I finished a film and went back and looked at it, I had changed as a person.
