That's the issue that I've been exploring: How did the Republic turn into the Empire? That's paralleled with: How did Anakin turn into Darth Vader? How does a good person go bad, and how does a democracy become a dictatorship? It isn't that the Empire conquered the Republic, it's that the Empire is the Republic.

Each time I do a trilogy it's ten years out of my life. I'll finish Episode III and I'll be 60. And the next 20 years after that I want to spend doing something other than Star Wars. If at 80 I'm still lively and having a good time and think I can work for another 10 years between 80 and 90, I might consider it. But don't count on it. There's nothing written, and it's not like I'm completing something. I'd have to start from scratch. The idea of a third trilogy was more of a media thing than it was me.

The influence of 'Hidden Fortress' comes up a lot because it was printed in a book once. The truth is, the only thing I was inspired by was the fact that it's told from the point of view of two peasants, who get mixed up with a samurai and princess and a lot of very high-level people.

I have a strong feeling about interesting people in space exploration. . . . And the only way it's going to happen is to have some kid fantasize about getting his ray gun, jumping into his spaceship, and flying into outer space.

The script is what you`ve dreamed up - this is what it should be. The film is what you end up with.

Most organisms either adapt and become part of the system, or get wiped out. The only thing we have to adapt to the system with is our brain. If we don't use it, and we don't adapt fast enough, we won't survive.

The object is to try to get the (movie) system to work for you, instead of against you. And the only way you can do it is through success, I'm afraid.
