There were a lot of people who thought that it would never happen; that Ridley Scott's follow-up to his sort-of Alien prequel, Prometheus, was doomed to linger in development hell forever - a project that would never quite find a way to find itself properly green-lit. But then came the news: Scott was still interested in making the follow-up, despite the fact that he opted to direct three unrelated movies in the aftermath of the film's release, and 20th Century Fox even plan to unveil the picture ahead of Neill Blomkamp's Alien 5.
