WonderCon 2012: Prometheus full-length trailer debuts

Earlier today, a minute-plus IMAX trailer hit the Internet, offering fans their first peek at the film's dialogue and a number of new sets. Now, the full two-and-a-half-minute trailer is out there on the Internet for all to see, and as Batman & Robin artist Cameron Stewart said on Twitter, it's chilling. Check it out below!
