However, it doesn’t sound as if we should expect the follow-up to bring that plot thread to a resolution. Promoting The Martian, Scott confirmed that there may be as many as three Prometheus sequels on the way as he continues to explore the history of this world.
“Yes,” Scott said when asked if Prometheus 2 will connect to Alien, “but it won’t be in the next one. It will be in the one after this one or maybe even a fourth film before we get back into the ‘Alien’ franchise… The whole point of it is to explain the Alien franchise and to explain the how and why of the creation of the Alien itself. I always thought of the Alien as kind of a piece of bacterial warfare. I always thought that that original ship, which I call the Croissant, was a battleship, holding these biomechanoid creatures that were all about destruction.”
This is a very interesting revelation, and indicates that Scott intends to build up to the events of Alien through these Prometheus movies. More plot details about the sequel will hopefully be revealed soon, as shooting begins next February, with Michael Fassbender and Noomi Rapace set to reprise their roles. Alien 5 is also on the way from director Neill Blomkamp.
