Adapting journalist Rajiv Chandrasekaran's book Imperial Life in the Emerald City, screenwriter Brian Helgeland's narrative jumps between hard-hitting action sequences and less-than-hard-hitting scenes of politically loaded dialogue. It's March of 2003, and Chief Warrant Officer Roy Miller's (Matt Damon) job is to track down WMDs in Baghdad. The only problem--and you'll never see this coming!--is that whenever he gets to a place where WMDs are supposed to be, there's jack shit. Green Zone works when it deals not with simplified moral quandaries, but rather when it's dominated by director Paul Greengrass' action chops: His camera feverish and eager, Greengrass' action scenes burst with momentum and catharsis. by Erik Henriksen
