"And Lucas is not a part of Hollywood."
One thing to admire about him is that he has the balls and the brains to fund his own movies. They're his, not a studio's. If other film makers were compelled to put their money on the line, they'd be more apt to think more about how the money-paying public will react, and to shape the movie accordingly. At least a little?
The last two Star Wars movies weren't great IMO, but Lucas was being true to his idea of making kids' movies. He thought about his audience and made age-appropriate movies.
Coppola tried it...and lasted one movie (One From the Heart).
