George Lucas reveals what he would have done with episodes 7 - 9
"[The next three Star Wars films] were going to get into a microbiotic world. But there’s this world of creatures that operate differently than we do. I call them the Whills. And the Whills are the ones who actually control the universe. They feed off the Force.
"Back in the day, I used to say ultimately what this means is we were just cars, vehicles for the Whills to travel around. We’re vessels for them. And the conduct is the midi-chlorians. The midi-chlorians are the ones that communicate with the Whills. The Whills, in a general sense, they are the Force.
"If I’d held onto the company I could have done it, and then it would have been done. Of course, a lot of the fans would have hated it, just like they did Phantom Menace and everything, but at least the whole story from beginning to end would be told."
