This scared the crap out of me when I first heard it. I hazard to guess this scene leads on from what we see in trailer, when everything goes to hell on the alien ship.
Ridley Scott, director of “Alien” and “Blade Runner,” returns to the genre he helped define. With PROMETHEUS, he creates a ground-breaking mythology, in which a team of explorers discover a clue to the origins of mankind on Earth, leading them on a thrilling journey to the darkest corners of the universe. There, they must fight a terrifying battle to save the future of the human race.
