"According to a bonus feature on the new Steelbook Blu-ray edition of Prometheus the answer is a confirmed yes, there is a connection between the Weyland Corporation and Blade Runner’s Tyrell Corporation [click the link to view], and proof that Blade Runner and the Alien movies take place within the same universe. This is something we’ve been speculating about since before Prometheus was released, thanks to a couple of videos released back in April."[/I]

[I]Prometheus blu-ray that was cut from the film. It clearly establishes a relationship between Eldon Tyrell and Peter Weyland, that they parted ways professionally, and that they both went on to be gods in their own right, creating life from nothing, coming to similar results through slightly different technologies.

Here’s an image of the speech:

If your find it difficult to read, here’s the relevant bit:

“A mentor and long-departed competitor once told me that it was time to put away childish things and abandon my “toys.” He encouraged me to come work for him and together we would take over the world and become new Gods. That’s how he ran his corporation, like a God on top of a pyramid overlooking a city of angels. Of course, he chose to replicate the power of creation in an unoriginal way, by simply copying God. And look how that turned out for the poor bastard. Literally blew up in the old man’s face. I always suggested he stick with simple robotics instead of those genetic abominations he enslaved and sold off-world, although his idea to implant them with false memories was, well… “amusing,” is how I would put it politely.”

This seems pretty cut and clear–references to standout scenes and visuals from Blade Runner can’t be ignored in this speech–which would make some sense. History has quite a few examples of mentorships that mature into professional rivalries between great minds trying to tame grand ambitions. So why not with Tyrell and Weyland? In the case of their androids, a mentorship under Tyrell would go far in explaining why all three films continue to present machines that are more human than human.

In an interview with Movies.com, Charles de Lauzirika, who directed all the additional content for the home edition for Prometheus, was asked about this speech in Weyland’s inbox and said, “That was me having fun and being cutesy. [Laughs] I wrote all that stuff.” But is it still considered canon? Scott hasn’t answered one way or another. He’s dodged the question and refuses to give a definitive answer. But if the themes and content of his films and their sanctioned supplemental materials are to be believed, Roy, David and Ash are cut from the same cloth, seeking the same experiences, whether aboard a hostile ship or walking the decrepit streets of a sun-blocked Los Angeles.
