Ridley Scott has not been shy with sharing major details concerning the future of the Alien franchise. The follow-ups to the divisive prequel Prometheus will kick off with Alien: Paradise Lost, and they will focus on expanding the already-extensive universe.
Scott previously said that he sees the four potential Prometheus sequels as investigations into the mechanics and intent behind these intimdating creatures, describing them as "bacterial warfare." Now, IGN reports that along with the "how" and "why," the future movies will directly confront the question of just who made these things.
Prometheus 2 will start getting shot in February and I’ve already begun now so I know what the script is. Then there will be another one after that and then maybe we’ll back into Alien 1, as to why? Who would make such a dreadful thing?
When it comes to the origins of Xenomorphs, I've always liked Carlos Poon's breakdown of the interspecies mating in Prometheus.
With Scott committed to building a much larger backstory, however, it seems that the young Xenomorph that we see in the prequel may have just been a callback to the original franchise.
Since the final sequel will abut the original Alien, I'm expecting some thorough explanation with a creation story and how that fits into the Engineers' overall society. Yet, I feel bit conflicted. I've always appreciated the terrifying unknown that has surrounded the Alien movies, but at the same time I trust Scott to give us a satisfying ending/beginning.
