I finally got into the film business in the 70s. Stanley Kubrick had amazed everybody with his beautiful film 2001:A Space Odyssey and I found myself working on a similar film for a young guy called George Lucas. He kept talking about robots, or swords made out of light, and super fast spaceships, and I kept saying, "Sure,George, but how are we going to make it?" well, in the end we found a way and Star Wars was a massive blockbuster.
