Prometheus is a new science fiction movie directed by Ridley Scott set to release between May 30, 2012, and June 8, 2012, by 20th Century Fox. A prequel to the 1979 classic movie Alien, Prometheus is one of most highly anticipated films of the year.

A major reason for this is how the studio and Scott have done a great job keeping the project under wraps and built buzz through intelligent marketing. They’ve steadily rolled out teasers, trailers, and even a corporate web site for the fictional company Weyland Industries to build anticipation, giving away enough information to leave viewers in suspense but not spoiling the story.

Whether Prometheus lives up to the hype is yet to be seen, but it is arguably one of the best, if not the best, marketed films of all time. Here are the four major teasers and trailers, including three released over the March 17 weekend. Note how they unravel the story bit by bit.

This fictional video clip of Weyland Industries’ founder and CEO Peter Wayland at the TED conference in the year 2023 (not a typo) lays the philosophical groundwork for the Prometheus Project, androids, and other concepts featured in the Prometheus movie universe. It does not appear to be connected to the movie, but has created quite a buzz online.
