Alejandro G. Inarritu’s The Revenant opens December 25th. Leonardo DiCaprio gets another shot at the big prize. The Revenant is “partially based” on Michael Punke’s 2003 novel and is the story of fur trapper and hunter Hugh Glass, a man who survived a grizzly bear attack, was left for dead, who then crawled his way back to survival. In the hands of Inarritu, there is likely more to it than just an extreme tale of survival.
