Where did this deleted scene from Prometheus come from?

I hear that there’s a lot of footage that got scrapped during production of Ridley Scott’s “Prometheus”. An egineer here, some tentacles there, but just how much was cut? That’s the sort of question you ask when a BluRay is approaching release and with Prometheus scheduled to release on October 11th we’re bound to find some questions getting answered. Here you’ll find about 10 solid minutes of footage for Prometheus giving us another perspective at a few key moments in the film.
