And what reason did anyone have to think that Lucas could make a world-changing fantasy blockbuster? The only thing remotely similar on his resume was 1971's THX 1138, a bleak, weird film that had been dismissed as incomprehensible by the studio and bombed at the box office. So imagine being the studio executives when this bearded guy brings in his 200-page script that's a confusing mishmash of insanity and "borrowed" ideas. Even personal friends of Lucas admitted that they couldn't understand what the script was about.
The Original Story Was A Confusing Trainwreck
So the whole thing had started with The Journal Of The Whills. It left everyone totally baffled, so Lucas wrote a new treatment, this one 13 pages long, then eventually expanded that into a full-length script called The Star Wars. This first draft is sort of like Star Wars, in the same way that getting run over by a bus is sort of like driving a car. The right elements are there (wheels, road, etc.), but they aren't doing what they're supposed to.
The story follows a fat teenager named Annikin Starkiller. Annikin's dad drags him to the planet Aquilae, where they meet General Luke Skywalker. Almost immediately, Aquilae is attacked by the New Galactic Empire for reasons that we couldn't explain without a flowchart and an advanced understanding of post-Jedi-Rebellion economic policy. Two or three more flowcharts deconstructing Aquilaean politics would be needed to explain how General Skywalker loses the war, but Annikin and the General do manage to sneak away from the planet with the last remaining members of the Aquilaean Royal Family. By "sneak away," of course, we mean "get chased and shot down over Wookiee country," which leads to General Skywalker training a squadron of Wookiee fighter pilots to shoot down the Death Star.
