After a lot of struggling and sort of reflection I realized that the time you have to give is now, regardless of how old you are.

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 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.

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.

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.

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

The secret to film is that it's an illusion.
