Last year filmmaker Alejandro González Iñárritu won the best picture, best director and best screenplay Oscars for Birdman. His new film, set to open Christmas Day, is already getting Oscar buzz. The Revenant is a Western, set in the American frontier in 1823. It stars Leonardo DiCaprio as legendary explorer Hugh Glass. In the harsh, icy American wilderness, he gets mauled by a grizzly bear. A fellow fur trapper murders Glass' son and then buries Glass alive, leaving him to die. The movie chronicles the hero's struggle to survive, bent on revenge.
