The intervening years have made it clear that there was no real plan for a sequel to the 1977 movie Star Wars. There was no guarantee that it would be a hit, much less the saga it came to be. Before that year was out, though, science-fiction writer Leigh Brackett was working to construct a sequel. George Lucas nixed many of her ideas, and she died before the project could be finished, so the story was passed to others. So what was in Brackett's treatment of the story?
