The sciences are the 'how,' and the humanities are the 'why' - why are we here, why do we believe in the things we believe in. I don't think you can have the 'how' without the 'why.'

I'm the one who has to have everybody throw rocks at me all the time, so at least if they're going to throw rocks at me, they're going to throw rocks at me for something I love rather than something I think is not very good, or at least something I think is not finished.

I wanted to be a car mechanic and I wanted to race cars and the idea of trying to make something out of my life wasn't really a priority. But the accident allowed me to apply myself at school. I got great grades. Eventually I got very excited about anthropology and about social sciences and psychology, and I was able to push my photography even further and eventually discovered film and film schools.

Good luck has its storms.

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.

Human nature means battling constantly between being completely self-absorbed and trying to be a communal creature. Nature makes you a communal creature. The ultimate single-minded, self-centered creature is a cancer cell. And mostly, we're not made up of cancer cells.

I think crossing into the digital age is the big move for the industry. I think it will be the biggest thing that's happened while I've been making movies. I equate it to the invention of color or sound, and I don't see any other major technical process coming along and changing that.
