Apparently, included as part of the U.K. steelbook (people still buy those?) release of "Prometheus," a pretty interesting easter egg can be found (see below). In short, it's a memo from Peter Weyland that seems to suggest that his mentor was none other than Eldon Tyrell. As you know, he was the head of the Tyrell Corporation in "Blade Runner" who created the false memory replicants in the film. And the references in the memo of this unnamed man looking out from a "pyramid" in the "City Of Angels" make it pretty obvious what this is all about.
But holy shit, Ridley. One beloved franchise is already diminished in the eyes of your fans, why drag another one down too? Could we be looking at some kind of Marvel-esque cross-linking universe between "Alien" and "Blade Runner"? Or is this just a one-time wink to devoted uber-fans? Guess we'll see, but with Scott officially helming the developing "Blade Runner 2" that has original writer Hampton Fancher conceiving the story -- we wonder if they've come up with an early idea of what they want to do.
Anyway, check out the tease below, along with the Honest trailer for "Prometheus." [ScreenCrush]
