SO.......This poster may NOT be a fake. Here's a photo of the actual poster. For the record, Chernin Entertainment has been working with Fox on various projects and had a presence at ComiCon.

http://www.prometheus-movie.com/news/43SO.....I've done MORE research and it's quite apparent that Chernin Entertainment and Twentieth Century Fox are working together on various projects.
THIS POSTER IS LEGIT FOLKS.
Why would an unrelated production company make a poster for a film they have ZERO connection with.
IT'S LEGIT AND IT'S AWESOME.
