One of the things that will never get explained in the films is how Ben was able to retain his identity, because it happened somewhere between the third and fourth movies. I set up that this is a discipline that he learned from Yoda; Yoda told him how to do that.

Emotionally involving the audience is easy. Anybody can do it blindfolded: get a little kitten and have some guy wring its neck.

So this is how liberty dies. With thunderous applause.

Luke: Boy, it's lucky you have these compartments. Han: I use them for smuggling. I never thought I'd be smuggling myself in them. This is ridiculous.

I came from a very avant-garde documentary kind of film making world. I like cinema verité, documentaries. I liked non-story, non-character tone poems. And that's the film making that I was interested in.

Sometimes people are surprised to learn that most of the films I've made don't work. They've been released but nobody has ever seen them. Maybe 40 percent of them are very successful. That's a very high percentage; most people have maybe 10 or 15 percent of their films work.

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.
