The 2003 invasion of Iraq and the war that followed hasn't lacked for coverage by Western filmmakers, but award-winning director James Bluemel's new documentary "Once Upon a Time in Iraq" promises a different perspective. The film is constructed of eyewitness accounts from Iraqis from all different backgrounds, who share their stories of what it meant to survive those violent years from the fall of Saddam Hussein to the end of the Islamic State Group.
