The Divide Trailer

Shooting of The Divide has started only a week ago, so we'll have to wait a bit before a full-length trailer. But we may already enjoy this first official teaser trailer of the Divide:

THE DIVIDE

To survive the end of the world they must first survive each other.
The Divide is going to be a damn intense movie! Any idea what may have cause the initial apocalypse? Nuclear strike? or natural disaster? maybe a meteor? And who are those people in hazard suits? This teaser trailer of the Divide raise more questions than answers! We're really teased!
