Green Zone is a 2010 action thriller film directed by Paul Greengrass and written by Brian Helgeland, based on the 2006 non-fiction book Imperial Life in the Emerald City by journalist Rajiv Chandrasekaran. The book documented life within the Green Zone in Baghdad during the 2003 invasion of Iraq. The key players in the film are General Mohammed Al-Rawi (Yigal Naor), who is hiding in Baghdad during the invasion of Iraq, and US Army Chief Warrant Officer Roy Miller (Matt Damon), a Mobile Exploitation Team (MET) leader who is searching for Iraqi weapons of mass destruction (WMD). Miller finds that the majority of the intel given to him is inaccurate.
