So, that apparently confirmed Neill Blomkamp Alien sequel? It may not be so advanced in production as we thought – and it may never happen.
In an interview for French site Allocine (Google Translate in English), original Alien director and more recent franchise prequels Prometheus and Alien: Covenant director Ridley Scott said that “There was never a a scenario,” apparently referring to reports of a completed script, but “only an idea that evolved into a pitch of ten pages.” Scott was involved as a producer, but Fox decided not to proceed with it, since Scott was already involved in the prequels.
Blomkamp wanted to insert his movie as a specific sequel to Aliens, the second film of the franchise, somehow nullifying both Alien 3 and Alien: Resurrection. And he had star Sigourney Weaver on board as well. But Blomkamp tweeted a reply to a fan asking about the likelyhood of the project moving forward, where he only said one word – “Slim”.
