Part 4/10:
This massive, complex mythology did not come from nothing; it was cultivated through decades of novels, comics, video games, and other media. George Lucas’s own treatments and story outlines, including details for episodes 7, 8, and 9, were rooted in this extensive source material.
Evidence from George Lucas and Lucasfilm
Lucas himself stated that he possessed numerous story treatments and had entrusted a "treasure trove" of ideas to Kennedy, including hundreds of books and comics. During interviews, Lucas confirmed the existence of these materials, emphasizing their potential for future storytelling:
"I have story treatments of seven, eight, and nine, and a bunch of other movies. We have hundreds of books and comics... I sort of moved that treasure trove of stories to Kathy."
