The Clone Wars
From a New York Times interview with George Lucas:
For Mr. Lucas this was an opportunity to revisit imaginary turf that gives him great personal satisfaction. “Star Wars,” he said, is “a sandbox I love to play in.”
“It’s not a matter of trying to prove anything to anybody,” he added. “I don’t have to.”
He’s right. He can do whatever he wants, and even if interest in the franchise wanes, it’s a sure bet that these projects will be profitable.
