Director Roland Emmerich likes to destroy the world, so it's no surprise that he's bought the rights to a new alien-invasion pitch titled 'Emergence.' After all, how could the director of 'Independence Day,' 'The Day After Tomorrow' and '2012' say no to what's described as a "large-scale, contemporary science-fiction film"? Large scale? That means Emmerich will be able to do what he does best: wipe out entire cities. Again.
