News about Ridley Scott's two Alien prequels have been floating around for some time. First it was one standalone prequel, then it was announced he was planning two films, then one again, and now it appears that one of those prequels has metamorphosed into a "seemingly" separate science fiction project called Prometheus (more on that in a second). Well, some casting news has just trickled in for it and if your interest in these movies hasn't already dissipated, read on.
The Hollywood Reporter has just confirmed that Michael Fassbender, best known for his roles in 300 and Inglourious Basterds, will be starring opposite Noomi Rapace, otherwise known as The Girl with the Dragon Tattoo, in Scott's ever changing sci-fi film. This news officially takes Fassbender out of the running for a key role in Universal's upcoming Snow White and the Huntsman, presumably due to conflicting shooting schedules.
Of interest, however, is that Prometheus may not be a total departure from the Alien series, as Sky Movies is reporting that the classic alien creatures actually play a major role in the film's plot. A source close to them even went so far as to say that the film "definitely takes place in the same world as Alien." How the two mix into each other remains to be seen.
