It's been fun calling Ridley Scott's Prometheus an Alien prequel/not-prequel.  The movie started out as a straight-up prequel to his classic 1979 sci-fi horror film, but then turned into something of a quasi-spin-off when Scott said back in January, "The keen fan will recognize strands of Alien’s DNA."  In a recent interview with the Wall Street Journal's Speakeasy blog, Scott says the last eight minutes of Prometheus will evolve into "a pretty good DNA of the Alien one."Hit the jump for more on what Scott had to say about the film plus my speculation on what will happen in the last eight minutes.  The film stars Charlize Theron, Michael Fassbender, Noomi Rapace, Idris Elba, and Guy Pearce.  Prometheus opens in 3D on June 8, 2012.alien-movie-image-space-jockey-01Scott tells Speakeasy the title "Prometheus" comes from the Greek myth of Prometheus, a titan who stole fire from the gods, gave it to man, and then was punished by having his liver eaten by a giant eagle on a daily basis.  This myth ties into the film's central metaphor of stealing from the gods and then being punished for that theft.  "Fire is our first form of technology," Scott says, and so by taking fire, the higher being is punished "in perpetuity in a horrible fashion."Some other quick notes:- There won't be a Ripley (Sigourney Weaver) cameo.- Scott says that the use of 3D and CGI has "completely taken off into this cyberworld" and says working on Prometheus was "the best time I’ve had in a number of years making a movie."  However, Scott adds "I’m a great believer in filming the real thing if you can and so I did a lot of building the real thing."  You may recall that some of the production took place in Iceland.Now to my speculation: Judging by the footage Adam and I saw at Comic-Con and Scott's long-held desire to base his prequel on the "Space Jockey" (above, right) seen near the beginning of Alien, I believe the final eight minutes will take the surviving characters to the Space Jockey.  A "keen fan" would instantly recognize the creature, but I believe the xenomorphs won't be in Prometheus.  This is all is just a guess on my part.  I have no idea what the film's ending will be.Here's the official and ridiculously vague synopsis for Prometheus
