Casting the right actor for the right part is some unspoken thing between the two of you to communicate.

In 'The Way Back' survivors were all ordinary people, and that's the whole point, that's who I felt these people should be, and they shouldn't be that hero that stands out.

You get very little from the studios anymore, it's all independent. And I think the studio, with the exception of something like The Social Network, a fine film, very interesting, but as for studio pictures, that's it, what else? There was more only a few years ago. So it changes, and I'm trying as much as I can.

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.

I carve stone. I've got hammers and chisels and I carve from sandstone. I just did a big mural of birds and trees.

You can mix in certain sensitivities as a filmmaker.

Various studios are still shooting on film with digital grain and the DI negatives, it's not ideal. We should really be all film or all digital. But that being said, the old way of graining in the camera, now you can make changes like a painter. It's dangerous because you can ruin the film, you can over-fiddle. We've all seen films and gone 'what the hell is that?'
