I've become wary of interviews in which you're forced to go back over the reasons why you made certain decisions. You tend to rationalize what you've done, to intellectually review a process that is often intuitive.

Well, all these stars have their houses swept quite regularly by people who work in the surveillance security business. They come in and they look for bugs and things.

Casting is always critical but in this case, 'The Way Back', I was looking internationally to a degree for an interesting mix of gentlemen, Irish, Polish, Russian and American. Not many people had the qualifications, people who would play the game, particular to this industry. So I had to research amongst the cast. They had to be very very prepared as we had to start shooting as soon as we could, there wasn't any time to talk, and there would only be three or four takes.

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.
