And sources claimed Lucasfilm approached three filmmakers - Brad, director of animation The Incredibles and Mission Impossible: Ghost Protocol, Star Trek's JJ Abrams and Lucas' long-term collaborator and friend Steven Spielberg.
Brad tweeted at the weekend in reply to a follower who asked him: "Tell me your next one is the new Star Wars!"
Brad wrote: "Nope. A science fiction film. Not Star Wars. That said, Michael Arndt is a fantastic writer and Kathy Kennedy is a brilliant producer. I will be first in line to see the new Star Wars."
Spielberg told Access Hollywood: "It's not my genre. It's my best friend George's genre."
And Abrams told Entertainment Weekly: "I have some original stuff I am working on next."
