Jerry Bruckheimer and J. Michael Straczynski (BABYLON 5, CHANGELING) are allying to bring SHATTERED UNION to the big screen. It's based on a 2K game which is available HERE.

In the game, states secede from the U.S. and form their own governments that wage a civil war against each other after Washington, D.C., is wiped out in a nuclear blast and chaos ravages the nation. Players control one of the warring group of states -- the California Commonwealth, Republic of Texas and New England Alliance are three of the six -- or a European peacekeeping unit sent to reunify America.

The show garnered lackluster ratings but raised a rabid fanbase whose devotion resulted in a soon-to-be-released "Season 3" comic book series (from the show's masterminds). Like UNION, the JERICHO comics will chronicle a modern day Civil War in America.
