Paul Greengrass’s as-yet-untitled Iraq movie, to be inspired by the non-fiction novel Imperial Life in the Emerald City: Inside Iraq’s Green Zone” by Rajiv Chandrasekaran, has added new castmembers: Amy Ryan and Greg Kinnear, who will be joining the film’s star, Matt Damon, who last worked with Greengrass on the “Bourne” films. Ryan will play a reporter to Kinnear and Damon’s CIA operatives.

Greengrass and Brian Helgeland turned the premise into a fictional thriller set in the “Green Zone,” a walled and fortified area where U.S. troops stay during the Iraq occupation. There, critics say, flawed decisions are made because leaders are separated from the realities of life in war-torn Iraq.

Damon plays an officer who teams with a senior CIA officer to search for evidence of weapons of mass destruction. Ryan will play a New York Times foreign correspondent sent to Iraq to investigate the U.S. government’s WMD claims. Kinnear plays another CIA officer. Antoni Corone has been cast as a colonel.

So, what, Bourne flies to Iraq and kicks ass? Or something? One can only hope.
