"Green Zone" plays out as a war/thriller but is really built around the scams, for lack of a better word, that were the justifications for the Iraq War.
Set in the early days of the war, the film follows Chief Warrant Officer Roy Miller (Matt Damon), who leads a team searching from site to site for weapons of mass destruction (WMDs) using information from a "credible source" that no seems to have ever actually seen. Eventually Miller becomes involved in a conflict between two camps in the US intelligence community, one of which wants to broker a deal with an Iraqi general, and the other that wants the general dead. The general knows the truth about the WMDs.
As an action film, "Green Zone" succeeds reasonably well. We have shaky camera work and rapid-fire editing creating a sense of chaos in both scenes of conflict as well as drama in scenes of confrontation between characters.
The film's critical look at the Iraq War, exploring the deception, misinformation, and the consequences of intervention end up a weakness. The story here suffers from its being compressed and simplified into a film form, centering around one low level officer who seems to run around doing whatever he wants, and two far over simplified military intelligence camps. The film strains mightily to hit almost every criticism of this period in US policy, resorting even at times to a mere few lines of exposition, at the cost of testing the suspension of disbelief.
That said, Matt Damon delivers an adequate performance as Miller, a character torn between following orders and his growing doubts about the mission. There is suspense and several good action sequences. However real world situations such as this conflict are far more chaotic, at all levels, than the film portrays. And it seems highly unrealistic that an officer in the thick of things at that point in the war would be anywhere near the powers that be and the motivations for the actions as we now know them.
Perhaps they should have stuck with the action part and left more of the power struggles, political optics and outright profiteering of that time for a future film to delve into.
