I remember Sci-Fi conventions in the late 70's and there was this one character who was always around that gave off a hint of illegal activity. For example, he had plenty of 35mm trailers to sell at the convention that someone along the supply chain must have pinched from a local movie theater.
But I remember he claimed to have a script of, as I recall, the not-yet-released sequel to Star Wars. I think he wanted $25 or so for a copy of it. I read the first page but now don't remember what it conveyed. It was a typed thing and xeroxed like the linked document. It occurred to me pretty quickly though that the guy could just be passing along fan fiction (which I admit wasn't really a thing as far as I knew back then) and trying make cash off it. I mean even after the film came out he could claim the script must have been rejected....
A year or so later I read in the newspaper about him having been stabbed to death by a Star Wars fan who had befriended him — someone he had lead along with a whole string of lies like claiming he knew George Lucas and how he could pass along the kid's story ideas to him — things like that. The kid finally figured out he was being had and snapped.
The thing kind of freaked me out at the time but I had forgotten it until this xeroxed script just appeared on HN.
