I think the last one would have to be The Godfather because it was such a powerful story. There was lots of violence in it but I could take it because I thought there was a reality to it. It wasn't gratuitous, it was just these guys' story.
I was making a film called The White Tower at the foot of Mont Blanc - the one thing I learned from that experience was that it's more difficult to go down a mountain than to go up. A lot of people don't realize that.
