Director of the Bourne series, Paul Greengrass, delivers a gritty, politics-driven dramatization, focusing on an early period of the US-led occupation of Iraq, back in 2003. Loosely adapted from Rajiv Chandrasekaran’s non-fiction title, Imperial Life In The Emerald City: Inside Baghdad’s Green Zone, the film opens with Chief Warrant Officer Roy Miller (Matt Damon—who’s still very much keeping in touch with his Bourne identity), a stoic, straight-talking soldier on the quest to locate elusive weapons of mass destruction (WMD).
