If you're going to perform inception, you need imagination. You need the simplest version of the idea-the one that will grow naturally in the subject's mind. Subtle art.

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.

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.

Particularly, the actors, to have analyzed the script in great detail from the point of view of their specific character. So that they have a handle on exactly where the character is in the chronology of things. In that sense the actors become your best check on the logic of the piece, and the way in which it all fits together. They become essential collaborators. The main thing is you have to work with very smart actors.

In Hollywood there's a great openness, almost a voracious appetite for new people. In England there's a great suspicion of the new. In cultural terms, that can be a good thing, but when you're trying to break into the film industry, it's definitely a bad thing.

I don't ever like to feel myself in the position to demand of an actor that they trust I'm going to do something worthwhile. I feel a responsibility to articulate what it is I'm going to do. Whether that's showing them a full script or sitting down with them and describing my ideas in detail. It's a very healthy burden on me as a film director to be able to articulate what I want to do, to inspire actors, rather than just saying, take it on trust I'll be able to do something worthwhile.

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.
