Before I became a film major, I was very heavily into social science, I had done a lot of sociology, anthropology, and I was playing in what I call social psychology, which is sort of an offshoot of anthropology/sociology - looking at a culture as a living organism, why it does what it does.

When Star Wars became a hit and I had a chance to make the other movies, I had to figure out a way to bring Ben back, but a lot of the issues he had to deal with were carried by Yoda. In a sense, I combined Yoda with the spirit of Ben. I wanted Ben to have some kind of influence, but I didn't want it to be a direct influence where he could help Luke. So Ben has managed to keep his identity after he became one with the Force. One of the things he was doing on Tatooine besides watching over Luke was learning how to keep his identity after he became part of the Force.

Working hard is very important. You're not going to get anywhere without working extremely hard.

I think crossing into the digital age is the big move for the industry. I think it will be the biggest thing that's happened while I've been making movies. I equate it to the invention of color or sound, and I don't see any other major technical process coming along and changing that.

You have to find something that you love enough to be able to take risks.

Part of the reason my friends and I became successful is that we were always helping each other.

Our system of education is locked in a time capsule. You want to say to the people in charge, 'You're not using today's tools! Wake up!'
