9. Its In The Same Universe As Blade Runner - Prometheus
The Crazy Theory: Prometheus wasn't just a quasi-prequel to Alien, but to Blade Runner too. Last year's critically liked, fan despised blockbuster ended up linking together Ridley Scotts two biggest sci-fi.
Why It Cant Be True: Theres so many reasons. The theory stipulates that the buildings behind the hologram of old Weyland are the skeletons of 2019 LA. Ignoring that the timeline doesn't match up at all - Blade Runner is set a good eighty years before Prometheus and androids have devolved in that time - thats a tenuous link. The buildings are typical sci-fi; nothing about them screams Blade Runner, beyond the orange colour (which was chosen to contrast Earth with LV-223). This leaves us really with just the easter eggs in the film, most concrete a note hidden in the DVD that shows Weyland acknowledge Eldon Tyrell. This makes Prometheus a straight sequel to Blade Runner, despite all other evidence pointing to something different. With so much conflicting arguments its clear these are just fan pleasing in jokes taken out of hand. For now at least. Who knows whatll happen when the upcoming sequels to both films arrive.
