Want to bet this guy isn't what he says he is?Director Paul Greengrass, best known for his success with the action-packed Jason Bourne franchise, also starring Damon, and the 9/11 film "United 93" brought in veterans from Iraq and Afghanistan to play secondary roles in "Green Zone." Some were selected from the anti-war group of returning soldiers, "Iraq Veterans Against the War."
Robert Miller, who served in the Army's 82nd paratrooper unit from 2001 to 2005 was one of the Iraq veterans who was cast as a soldier in the movie. He says he thinks it is unfortunate that some critics are painting the film in a negative light.
