Not many people can claim they've truly shaped popular culture, but George Lucas can. His creation, Star Wars, didn't just render an entire fictional universe, but also a full-fledged cultural phenomenon. Total ticket sales alone are in the billions, and the franchise has brought more than $32 billion to retailers through related novels, video games and fan projects galore. (One recent project merged Star Wars with the iconic Sgt. Pepper's Lonely Hearts Club Band album by The Beatles.)

"I am simply trying to struggle through life; trying to do God's bidding."

"It's hard work making movies. It's like being a doctor: you work long hours, very hard hours, and it's emotional, tense work. If you don't really love it, then it ain't worth it."

"Making a film is like putting out a fire with sieve. There are so many elements, and it gets so complicated."

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

"From being a struggling, starving filmmaker to being incredibly successful in a period of a couple of years is quite a powerful experience, and not necessarily a good one."

"I hate corporations and I'm not happy that they have taken over the film business but on the same hand I find myself being the head of a corporation. There's a certain irony there."

"I took over control of the merchandising not because I thought it was going to make me rich, but because I wanted to control it. I wanted to make a stand for social, safety and quality reasons. I didn't want someone using the name Star Wars on a piece of junk."
