Ridley Scott offered a few specifics about his still-untitled Alien Prequel in an interview with The Independent.
“The film[s] will be really tough, really nasty,” says Scott of the proposed two-part prequel, which he says will take place 30 years before the first film, “It’s the dark side of the moon. We are talking about gods and engineers. Engineers of space. And were the aliens designed as a form of biological warfare? Or biology that would go in and clean up a planet?”
Scott refers to the first film’s Space Jockey, part of a mysterious race of giants that carried the alien egg as their cargo. A mystery in the first film, the creature’s origins have not been explored in subsequent entries to the franchise.
Two prequel films are being prepped to shoot back-to-back in 3D. The original script comes from Jon Spaihts with Damon Lindelof currently doing touch-ups.
