I'm still believing that a literal link to the world of Blade Runner will be established in Prometheus...a mention of the Tyrell corporation by name, etc...
There's some HUGE things we're not being told...grand revelations...of which reminds me. Patrick Wilson said this
"It was an absolute thrill," Wilson said of his time on Scott's set. "I was blown away by [the script] and I don't use that sort of phrase a lot, but I was blown away by it, so excited that I wanted to read it again. I just kept re-reading it, even though I knew what was coming. And put it this way, I've never done this, I've never finished the shooting on a movie, and then on the ride home read the script again. I had no reason to read it, it was not work-oriented, I just really loved it, it's so cool."
