The events of 9/11 had a massive effect on me, like everyone, and I wanted to use my position as a filmmaker to contribute something so they are not casually forgotten. By honoring the families who lost those they loved, I hope we can ensure that their sacrifice is remembered and hopefully seek wisdom in the future.

Whatever your style or subject matter, in the end, film-making is about searching for authenticity - that is what the audience will divine.

Deep down, all directors feel like frauds - because it's built into the nature of the job. You're the jack of all trades and the master of none. The cameraman knows the camera, the sound man knows the sound equipment - and you? You can't do anything: You can't do the acting, you can't dress the set, you don't record the sound or shoot the images.

This new global economy, it's all based on the sea routes.

All directors make films in individual ways. But the classical kind of view of filmmaking is that you have a script, and it's very linear. There's a script, then you're going to shoot the script ,and then you cut that, and then that's the end of the film. And that's never really been how I've seen it.

I don't want to feel what I'm creating on film has an outcome that is preordained. I don't think of the world as a place with a divinity that shapes our end. What you try to do with film is create, as far as you possibly can, an unfolding present - a theatre in which an outcome happens and is tested.
