'THE LAST MOUNTAIN is a spellbinding tour along the frontlines of America's most spirited battle over the environment and the economy. Set deep in the heart of Appalachian West Virginia, this consciousness-raising film captures a rowdy band of citizens as they try to stop a giant coal company from blowing up a pristine mountain for its coal. A tale of greed and courage, folly and forward-thinking, THE LAST MOUNTAIN is brimming with the coal hard facts and vivid testimony from the hardscrabble people whose lives are intertwined with coal. Featuring environmental activist and lawyer Robert Kennedy Jr. and the stunning visuals of Appalachia, THE LAST MOUNTAIN is ''informative, stirring, and most importantly, inspiring'' (Hollywood Reporter). Not only a searing indictment of America's energy policy, this powerful film also points the way to a brighter, greener future. '
