The film opens in April, 2003 in Baghdad, Iraq. Matt Damon as U.S. Army Chief Warrant Officer Roy Miller and his men are on their second search for WMD (Weapons of Mass Destruction). The place or neighborhood is called Diwanyia. Another Army unit sustained some casualties so Miller’s unit could access the site. Their search is going to not turn up anything related to WMD, despite the fact that the ‘intel’ that Miller has been given, had come from a ‘reliable/trusted’ source, and had been vetted; so they said. Soon, Miller will again come up without any results at a place called Al Mansour. And that’s when he begins to think about what is going on. When he questions the higher ups about the flawed intel, he’s told: Button it up, the intel is fine – just do your job.
This is how the Paul Greengrass helmed Green Zone begins. Brian Helgeland has the screenplay credit and Rajiv Chandrasekaran is the author of the 2006 non-fiction book Imperial Life in the Emerald City which was the source or inspiration for the film.
