In Bruges star Brendan Gleeson has been cast for the final lead role in the untitled Green Zone thriller that Paul Greengrass is directing for Universal and Working Title. Gleeson joins Matt Damon, Greg Kinnear, Amy Ryan and Jason Isaacs.

According to Variety, the Brian Helgeland-scripted drama is a fictionalized drama inspired by the Rajiv Chandrasekaran book "Imperial Life in the Emerald City," and 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.

The film will shoot in Spain. No date has been set.
