As Ridley Scott and his fellow filmmakers continue making the press rounds for his upcoming science-fiction, The Martian, based off the fantastic Andy Weir novel, Ridley Scott is starting to talk more about Prometheus 2. In an interview with Collider, Scott talked about the questions Noomi Rapace’s Elizabeth Shaw and Michael Fassbender’s David 8 will have when they reach their destination in Prometheus 2:

“It starts off with a very grand idea—or a grand question, really. Who are they and why did they create such evil biology and bacteriology? And [in creating], to protect themselves from what? So the questions are answered there, or rather, beginning to be answered in Prometheus 2.”

Much of the story for Prometheus 2 is unknown. The last we heard of the screen writing was that Michael Green had written a script by Jack Paglen. Scott recently told interviewers that Prometheus 2 would start production in February 2016 and that he had been scouting for locations in Australia.
