The combination of this video being of such bad quality plus the temporary titles indicates that this might be a genuinely early cut of a teaser for Ridley Scott‘s Prometheus (20th Century Fox, 6.8.12), which is some kind of Alien prequel. We all remember the Alien scene when three Nostromo crew members enter the huge, horseshoe-shaped ship and come upon a dead giant with big shoulders and a big head and an elephant trunk. I’ve watched this trailer twice and haven’t spotted any of those elephant-trunk guys walking around.
Prometheus stars Noomi Rapace, Charlize Theron, Michael Fassbender, Guy Pearce, Idris Elba, Kate Dickie and Ben Foster.
