But through George Lucas' devotion to an acid flashback he was apparently having for three straight weeks, when production wrapped, he found himself with a masterpiece of celluloid, right?
Nope! Turns out that the first cut of Star Wars was an incomprehensible mess, and it was up to George's wife and editor, Marcia Lucas, to swoop in and save the day ... again.
Actually, Marcia was Lucas' "muse" through the entire production, if by "muse" you mean "person who had all the good ideas." It was her idea to kill Obi-Wan (apparently George's first draft had him just disappearing at one point) and demanded that Lucas keep the "For Luck" kiss scene that would snarl the series up in a knotty mess of incest once the third movie was released. But, most importantly, she's totally responsible for the Battle of Yavin, also known as The Death Star Trench Run scene, also known as The Part at the End of the Movie Where the Good Guys Win.
