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.

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?'

It's spiritual, a man that has a past and regrets, but you can as a director take a shot, and there's something in the eyes and the face, you just can't fake it, you can't teach it, and I think Ed Harris has that quality.

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.

Movies tie things up in an arbitrary length of time, but I have always liked things that aren't fully realised.

I don't know if there will ever be an ideal way of selling an original picture. Because everything you're doing, you're inventing.

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