As you may have heard, the Mayan "Long Count" Calender runs out on December 21, 2012, and some folks believe that date will usher in the beginning of the Apocalypse. This is catnip to director Roland Emmerich, who is perfectly comfortable destroying Earth even when he doesn't have an ancient prophecy to justify his end of day's scenarios.

Our friends at FilmDrunk have the latest trailer from Emmerich's inevitable 2012 film (creatively titled "2012"). It's some pretty serious disaster porn, with all the fireballs, earthquakes, tidal waves and John Cusack reaction shots you'd expect from the genre.

While it stands to reason that improvements in CGI mean "2012" will lay waste to earth like no movie has ever done before, we'll have to reserve that judgment until we see it on the big screen. For now, we're wondering what already-released film took the biggest dump on our home planet.
