Even in high school I was very interested in history - why people do the things they do. As a kid I spent a lot of time trying to relate the past to the present.

[Star Wars is] designed primarily to make young people think about the mystery. Not to say, 'Here's the answer.' It's to say, 'Think about this for a second. Is there a God? What does God look like? What does God sound like? What does God feel like? How do we relate to God?'

I was going to go to a four-year college and be an anthropologist or to an art school and be an illustrator when a friend convinced me to learn photography at the University of Southern California. Little did I know it was a school that taught you how to make movies! It had never occurred to me that I'd ever have any interest in filmmaking.

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!'

A lot of great thinkers- like Einstein and Newton- come up with their best ideas when they're young because they don't yet think in the way that the establishment teaches them. Sometimes your lack of knowledge frees your mind to be creative and think in a different way. But you still have to be logical and figure out a practical way to get things done, even though you're looking at things differently.

All of my films have been very hard to understand at the script stage because they're very different. At the time I did them they were not conventional. The executives could only think in terms of what they'd already seen. It's hard for them to think in terms of what has never been done before.

I felt that one of the major issues in the third film is that Luke is finally on his own and has to fight Vader and the Emperor by himself. If you get a sense that Yoda or Ben is there to help him or to somehow influence him, it diminishes the power of the scene.
