An Austrailian Movie site [What’sPlaying.au] earlier published Alien prequel script details on its page which evidently 20th Century Fox later instructed to remove adding legitimacy to the fact that the details may in fact be genuine. The site reviewed a copy of Damon Lindelof’s script for Alien prequel for Oscar consideration.
The site states the draft that Lindelof revised from earlier work by Jon Spaihts “bares little to no similarity to the previous [Alien] chapters.”
“The story follows a group of terraforming aliens the script calls ‘Growers’ — these are seemingly of the race from which comes the original film’s ‘space jockey.’ There’s a strange sequence in which the Growers use a bit of mind control to instigate a homosexual encounter between Fin and Karik, two male human slave farmers. The aliens, you see, are a single-sex species and don’t understand the male-female breeding requirements of humans.”
This does seem to confirm that the earlier leaked script Alien Harvest is legitimate. The title “Alien the xenomorph” is a creature used by Growers as part of the terraforming process, and at a point in the script it develops into the creature we know and love. So we won’t see it in the form we know right off; this will be a payoff later in the script. Into the group of Growers and human slaves comes a ship crewed by “the usual Alien misfits” complete with a female character that sounds like “Vasquez” from Aliens, and another woman named “Truks” that is reportedly the role for which Gemma Arterton was considered. Scott has also reportedly met with Lance Henricksen, [Bishop] though how the guy who fit into the established Alien storyline might work in this film, I can only conjecture. Essentially we are looking at a Spaihts storyline, and reminicent ot Vincent Ward’s contribution to Alien 3, Lindelof has been brought in to polish and tone down a very alternative take on the direction of the franchise. Expect the Script to surface somewhere soon.
