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.

By the time I was 10 or 11, I knew I wanted to make films.

What I love about IMAX is with its extraordinary resolution and color reproduction it's a very rich image with incredible detail. It lends itself wonderfully to huge shots with much in the frame. Thousands of extras and all the rest.

Say you have a headline like "Mountain Bike Stolen," and then you read the story, read another story about it the next day, and then the next week, and then the next year. News is a process of expansion, the filling in of detail, and making narrative connections - not based on chronology, but based on features of the story. There are narrative connections made between props, between characters, between situations, and so forth.

My approach with actors is to try and give them whatever it is they need from me. Direction to me is about listening and responding and realizing how much they need to know from me and how much they have figured out for themselves, really.

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.

To me, any kind of filmmaking that's reactive is not going to be as good as something more inventive and original.
