In ‘The Revenant,’ Leonardo DiCaprio plays 1800s frontiersman Hugh Glass (pictured here with a Pawnee Indian woman played by Grace Dove). The film, directed by Oscar winner Alejandro González Iñárritu, is based on Michael Punke’s 2003 novel of the same name. According to production designer Jack Fisk, a character that does not appear in the book was added to the film: Glass’s son.
