Ed Harris seemed to be as a man, it seems, like a Clint Eastwood, this country is one that has produced more than one of this kind of man that's iconic and enormously appealing to the world, as part of American film culture.

I'm not from a theatre background, I'm wary of rehearsals. But what I do like is hanging out together, on location.

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.

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.'

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 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.

Anybody I'd spoken to who'd been in Siberia said 'would you please put mosquitos in your film,' that's what everybody knows about, they're big and they're nasty.
