Brendan Gleeson has been signed on for the final lead role in the Paul Greengrass-directed untitled "Green Zone" thriller for Universal Pictures and Working Title says Variety.
Inspired by Rajiv Chandrasekaran's book "Imperial Life in the Emerald City," the drama focuses on the dichotomy between the Green Zone, where troops are housed, and the streets of Baghdad after the overthrow of Saddam Hussein.
The film posits that bureaucrats are making policy decisions about the country's rebuilding even though they're in a sheltered enclave without a clear view of all that is happening.
Gleeson, who will play an American soldier, joins Matt Damon, Greg Kinnear, Amy Ryan and Jason Isaacs. Brian Helgeland adapted the script and filming is underway in Spain.
