There's always been this strand of filmmaking in Britain which is like socialist neo-realism. That's always been there. I've never been part of that, really; I've been much closer to fantasy.

I love green. Green is the color of nature, trees. I'm a tree freak. I spend a lot of my time planting trees, nurturing them, and studying them. It's one of the colors I couldn't live without.

In the '60s and '70s it was a great period for American films because studios were still run by individuals who worked off the seat of their pants and went along with things. At that time, they were very uncertain about what to make because of the influence of television. A lot of really terrific movies were made. But then the studios gradually became more corporate and were owned by corporations and run in that way and now they're very nervous. You see what they make - sequels, franchises and try not to take risks.

The resistance to black-and-white is huge, in the way that you have to sell the film. It's difficult to distribute around the world.

It's so easy to manipulate an audience, but it's nearly always clear that you are being manipulated. I think even people that are not critically attuned are aware of cynical manipulation in film.

There are always forces at work in a society, certainly in America, which are really forces of censorship -either religious bodies or zealots who are always putting pressure on things, whether it's books or art or film. And all art is fundamentally subversive, because it upsets people's perceptions, their notions about society. Therefore, art is dangerous, but good art is always making us reassess our thoughts and feelings about how we relate to other people. There are always people who fear that and want to suppress that.

There were two sides to David Lean: on the one side, he was kind of a rather stiff, disciplined Englishman. And then he had this kind of romantic side to him. I think being true to both sides of your nature is important.
