The submarine genre is a category with all its own rules. But shooting on water is famously tough.
I don't think life gets any better than sitting in the sun while a legend of French cinema tells you stories about making 'Belle de Jour' and other wonderful films, and eating great food.
I suppose that the Western has always been a kind of mold to which you could pour the concerns of the day, but have them seen in the simple terms of the Western, of one alley or whatever.
It's so nice to be totally artistically free.
Every film that is made about the past is always a reflection of the present.
I remember going to the university film club to see 'The Life And Death Of Colonel Blimp' one night and being bowled over. It was one of the most beautiful films I'd ever seen. And it felt so personal.
People think that the Italians invented neorealism, but actually, Humphrey Jennings did. He was revolutionary in using non-professional actors in his films, and he got extraordinary performances out of them.
When I was growing up on Loch Lomondside, one of the first albums I ever bought was Marley's 'Uprising.' I guess that would have been 1980 - just before he died.
I think there's always been interest in Bob Marley.
Elvis Presley's estate is making 30 million a year, and they say that Marley shouldn't be, but he is from a much poorer part of the world, and a lot more people need the money.
I like to take a little of what I learned in fiction and apply it to documentary and vice versa.
I'm a cynical person who's normally attracted to the dark side of things.
If you go to pretty much everywhere in the developing world, you will find Bob Marley murals, and you'll find people playing his music.
It's interesting to me that the Arab Spring started in Tunisia, and in the marches, people were singing 'Get up, stand up, stand up for your rights.'
We should not confuse having a Flip camera with making a documentary.
I think we're all greedy. Who do you know who says, 'I have enough! I don't need any more!'? It's part of human nature.
When we made 'Life in a Day,' we asked people around the globe to record their lives on a single ordinary day. When we were cutting that film, we talked about what it might be like if we chose a day that already had significance to people. The result is 'Christmas in a Day.'
I was fascinated by making a submarine movie, inspired by the Kursk disaster. This idea of being trapped down at the bottom of the sea seemed so terrifying. I was very interested in making a sub film which wasn't a military film. You think, Well, why are they there, then, if they're not in the military? Oh, well, they must be looking for treasure.
The things that are hardest to shoot are the things where you want people just to feel very natural, and you want to do love scenes, and you want to do just kids hanging out and trying to get them to relax.
I recommend to any of you, that's always a good way to make a film: use the interesting bits.
