March 14, 2010 (San Diego's East County) -- Green Zone is relentlessly exciting from beginning to end. We know there never were weapons of mass destruction (WMDs) in Iraq, which was the primary reason we went to war. We know what the outcome will be in the end, that there’s no turning back and we’re in it for the long haul, WMDs or not. Despite this common knowledge, screenwriter Brian Helgeland manages to incorporate a mystery that keeps us guessing until the very end in addition to exciting action sequences.
