Just last week, we brought you the new trailer and a behind the scenes featurette for the Timur Bekmambetov (Wanted, Nightwatch) produced, Chris Gorak (Minority Report) directed Sci-Fi film, The Darkest Hour. Now, Summit Entertainment and 20th Century Fox have released some new alien warning signs and a new TV spot for the film.

The signs are very reminiscent of those used in the 2009 Neill Blomkamp film District 9. Check them out below!
