Yeah, so I read the Alien Harvast script all the way through... It's awful. It is all over the place. It's entirely too preoccupied with sex and not hardly at all occupied with any substantive details about the Space Jockies or the Zenomorphs. It goes off in a dozen places that you'll find you care nothing about. It's bland. It's dull. It's a little too convienant in providing the back story Alien. It reads nothing like either Passengers or Shadow 19 wich have been authenticated as being written the scriptwriter Scott and Lindelof mention in the AMC interview. I doubt it's real or that it has anything to do with Prometheus.
