The Extended International Trailer for Prometheus Tells Us More Than Ever

It's only been since Friday since I've posted something about Ridley Scott's Prometheus, but believe me this new extended international trailer is definitely worth watching. It explains a lot more about the movie than anything we've seen yet.

The basics: Charlize Theron is a corporate type who seems to be in charge of everything and everybody,but Idris Elba is still the man, who also does the crew of the Prometheus a favor by piloting the ship, and there are some snake-like life forms that have a bite that can fuck you up. Notice the comment somebody makes that "they're changing". What are they changing to?
