What we love that 'The Way Back' is not subsidized, it's alive and kicking. And if I can't make the kind of film that I want to make, then the hell with it, I've had a great run. But I'm more concerned with the younger people coming up that want to make this kind of film.

With war and famine and flood and special effects films, when you do somebody under duress, you have to be really be inventive and the risk of keeping it very simple is you might loose some of the audience because it's not overt, it's hidden, not coming at you. Then you might cut through to some of this numbness and reach something profound and tragic.

I think Ed Harris is a conscious screen actor, so I think it was strong, it was like he put everything together somehow in 'The Way Back'. He likes, I don't want to say the method approach, because that's not really necessarily his way of working, but it was easy to do because of the location. He'd go off by himself, and they would make things.

The smallest detail can contribute to the whole, I think particularly with emotion, you want it to be as authentic as it can, whether its a artifact or a theatrical event. But the whole is the sum of so many images.

Silent films were, I think, more different than we know to sound films. We think of it as simply that we added dialogue and in actual fact I think it was an entirely different art form.

Sixty-five days principle photography, five-day weeks, which is the only way I'll work. With my cinematographer Russell Boyd, we take as much time as possible before pre-production, looking at stills. The next most important thing: he will come to me and talk about lenses. And I'll see his plan, which is generally great, and I might talk about how the light will be, handheld or not? I talk very freely, and try not to talk specifically, just talk around it, because it can unlock all sorts of things.

You can mix in certain sensitivities as a filmmaker.
