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.

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.

With fiction, I've grown to really love the challenge of lying, the challenge of telling a good tale that isn't truthful, and working with performers is endlessly fascinating. You know, learning what a good performance is, how to get a good performance, how much or how little you need to create emotion or to create character.

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.

We grew up during the 'peace and love' of the 1960s, only to discover that there are wars everywhere, and love and romance is a con.

The Industry's at war. I think it's about control. You can make all of the financial arguments that the industry has been shooting itself in the foot, but it is an industry built on a foundation of ownership and exploitation of intellectual property rights.

I vividly remember the stories my grandfather told me about the carnage of the First World War, which people tend to forget was one of the worst massacres in human history.

I don't think you can perpetrate war crimes with defensive weapons, with air defense systems.
