In this vintage featurette, Star Wars creator George Lucas discusses the origins and evolution of the Star Wars story. The original concept centered around a father and his twin children, and that relationship was the heart of the story. Lucas developed the story further, saying that characters "changed shapes and sizes," and it finally solidified into what Star Wars would become. However, he also reveals that he would often let the story and characters lead him, and "that's the adventure of writing -- the fact that you're not sure where it's going to go."
