My first experience with film was through a still camera. I would sit, very much against my will, with my father in the game reserve, watching some elephant or rhino or whatever, through a 400 millimeter lens and wait, and waiting and waiting.

When you're used to looking through a stills lens and you have to capture an emotional moment, and that picture is not moving and yet it has to have impact, I think that's the first influence on my style.

The first prize for any production is, if you can find a location that means you don't have to build sets, that will serve, and is not excessively expensive to hire, then it can save you a lot of money.

You can sustain visual beauty and innovative visual ideas for a certain length of time, but in a two-hour experience, which is really what movies are, usually audiences - whether they know it or not - most want an emotional connection to character.

The truth about people at every economic level of life is you get those who are kind and who are not, those who are greedy, whether they be rich or poor. That's a common thread through humanity on any street you go to.

This may sound melodramatic but I have never, ever worked so hard. The film will be released in a different country every week for the next six weeks. I've just come back from Germany, France and Sweden to be in LA for the nominations and to speak to the American press.
