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.

I could do John Wayne, Jack Benny, Jack Kennedy, Lyndon Johnson and entertain my friends. But I never seriously considered it as a career choice.

Bruce Lee' is the fastest film in my career. But the quality is also very high. The last song was shot continuously for 24 hours. We worked like robots for that song, but the quality is outstanding.

I've had the privilege of meeting and/or interviewing most of the top metal and hard rock artists at various points in my career and sharing their stories and music with millions of fans on air through TV and radio.

I've always been an entrepreneur, but it's never been about the money. I like a challenge, the harder the better.
