USA Today got a hint from George Lucas at his AFI lifetime achievement award gala about the new live-action "Star Wars" TV series. The series is expected to take place sometime between "Episode III" and "Episode IV".

Ford was approached by Daniel Logan, 18, who played young Boba Fett
in Episode II: Attack of the Clones. Lucas said Logan's character may
be included in his live-action Star Wars TV series, which is in the
works.

IESB.net also chatted with Lucas who said they are getting ready to go on the 3D half-hour version of the Clone Wars animated series is. "The live action will be, you know, a year or two later," he added.

Asked if we're going to see some back stories, like Knights of the Old Republic, in the series, Lucas said, "there is a possibility of that, but not in this series. You know, there's a possibility of more series if these work."[/a]
