I wanted Yoda to be the traditional kind of character you find in fairy tales and mythology. And that character is usually a frog or a wizened old man on the side of the road. The hero is going down the road and meets this poor and insignificant person. The goal or lesson is for the hero to learn to respect everybody and to pay attention to the poorest person because that's where the key to his success will be.

I'm not much of a math and science guy. I spent most of my time in school daydreaming and managed to turn it into a living. When I was making "Star Wars," I wasn't restrained by any kind of science. I simply said, "I'm going to create a world that's fun and interesting, makes sense, and seems to have a reality to it."

I've always tried to be aware of what I say in my films, because all of us who make motion pictures are teachers - teachers with very loud voices.

Rejoice for those around you who transform into the Force. Mourn them, do not. Miss them, do not. Attachment leads to jealousy. The shadow of greed, that is. Train yourself to let go of everything you fear to lose

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.

Although I write screenplays, I don't think I'm a very good writer.

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