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.

It doesn't take any imagination at all to feel awed

I've done a number of things that get categories closed off in a way, so when I read 'The Long Walk' by Slavomir Rawicz and decided to do film, 'I thought, you know, this is going to be wonderful,' two and a half years, three years, whatever it was.

In terms of how I work with actors, having worked so heavily on the script I have a very clear idea of the characters; they are reasonably well illustrated in the script. If you cast it right, to a great degree you can hand it over to the actor and I just make suggestions. I'm not the kind of director who needs or wants to get into too much finessing. Ideally, when you hit the set, you have this conversation, like, 'eh, what did you think?' 'I don't know, what did you think?' 'Why don't we just try it again, make a few physical changes.'

I always thought the editor should cut the film and so I'll come in and look at the movie. Just because that's the only way I can really see the ideas of the editor, it's really working together. Yes it's a hierarchy, yes I'm the boss, but I like to see and to think about the idea, and it's about us asking, 'do we have to say that?' and, 'how do we make it there?' So it's advising the editor, it's very give and take, it's very free, but in the end, it's wonderful once you get through the first couple of cuts.

So much of the work is intuitive. The resistance you detect is just that, a kind of evasion, a sense that too much analysis will inhibit creativity.

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.
