Lucas said Wednesday he's making an animated TV series of "Clone Wars" that could air next year, although he hasn't sold the show to a network yet.
The series is set during the time when the Republic is fighting a civil war against separatists led by Count Dooku.
The mythic period hasn't been dealt with too much in the popular "Star Wars" movies, so "it's a fun place to go," Lucas said.
"It basically has all the main characters" such as Anakin Skywalker and Obi-Wan Kenobi, Lucas said, but the stars who played them in the movies won't voice them for the TV show.
"There's nobody famous," Lucas told The Associated Press in a telephone interview.
The show is planned as a continuation of the Emmy-winning "Clone Wars" that aired in 25 episodes on the Cartoon Network from 2003 to 2005. That series used limited animation. The new version will use 3-D computer graphics.
It's one of many projects being pursued by Lucas, including a fourth "Indiana Jones" movie.
"We're working on it. We haven't agreed on a script yet," Lucas said.
