Changes are not unusual - I mean, most movies, when they release them, they make changes. But somehow, when I make the slightest change, everybody thinks it's the end of the world.

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.

Part of the reason my friends and I became successful is that we were always helping each other.

When you get a small group of fans who hate something, it becomes compounded by the internet. The press picks up the internet like it's a source. They don't realise it is just one person typing out their opinion.

You can't do it unless you can imagine it.

I think that Lethal Weapon-style dialogue is overused, it's a necessary aspect of high action films where you have to have the smart retort. You have to say "I'll be back baby" and stuff. It's not my style.

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.
