The Revenant (2015 film) [SEP] Introduction
The Revenant is a 2015 American epic western adventure film directed by Alejandro González Iñárritu. The screenplay by Mark L. Smith and Iñárritu is based in part on Michael Punke's 2002 novel of the same name, describing frontiersman Hugh Glass's experiences in 1823. That novel is in turn based on the 1915 poem "The Song of Hugh Glass". The film stars Leonardo DiCaprio, Tom Hardy, Domhnall Gleeson, and Will Poulter. Development began in August 2001 when producer Akiva Goldsman purchased Punke's manuscript. Iñárritu signed on to direct in August 2011 and in April 2014, after several delays which were due to other projects, Iñárritu confirmed that he was beginning work on "The Revenant" and he also confirmed that DiCaprio would play the lead role.
