I enjoyed Jonathan Franzen's 'Freedom.' Would I make that into a film? I think it's better suited to television. That would very much be a dialogue and performance piece, and it would take some very skilful direction - but not my kind of directing. But I thought it was a real literary work.

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 love a chance to shoot real locations, because in films in the earlier days before people traveled as much, it was exotic to see a film set in Switzerland, and that area has been taken over by CGI, mostly, and fantasy landscapes. It's unusual to see this much landscape, people say it's old fashioned. So what you're referring to is there was that period in the '50s and '60s when there were epics and you saw landscape.

I'm not from a theatrical background where people do like to work it out on some stage space.

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

I had always been wary of doing any autobiographical movies, truly feeling at home with fiction.

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.
