From Cosmic Book News:
Our DC Entertainment source has just given us a few tidbits on a possible new Star Wars spin-off movie.
Previously, our source let us in on a possible storyline for Star Wars Episode VII involving a disciple of Palpatine and the Skywalker/Solo children.
This time, the news is said to involve a Star Wars spin-off movie taking place between Episode III and IV.
Our source notes that the Lucasfilm friend who provided the information said the idea is being tossed around.
