Good luck has its storms.

I like to say that films are never finished, they're only abandoned.

If this were a fantasy world, there would be ten of me and we would each be doing what we wanted to do.

You have to understand that it's a very cooperative world, not only with the environment, with but our fellow human beings. If you do not cooperate, if you do not work together to keep the entire organism going, the whole thing dies, and everybody dies with it. That's a law of nature, and it's existed forever. We're one of the very few creatures that has a choice, and can intellectualize the process.

My success wasn't based on how I could push down everybody that was around me. My success was based on how much I could push everybody up.

For 'Star Wars' I had to develop a whole new idea about special effects to give it the kind of kinetic energy I was looking for. I did it with motion-control photography.

Success is a very difficult thing. It's much more difficult than one might think.
