Though the film is set in the 1820s, it has an apocalyptic feel thanks to all the war scenes, bear fighting and unkempt beards. Directed by Oscar-winning Birdman filmmaker Alejandro González Iñárritu, The Revenant follows frontiersman Hugh Glass (DiCaprio) as he sets out on a path of vengeance against those who left him for dead after a bear mauling.

One of the only lines DiCaprio says in the trailer really sets up what audiences are in for when the film hits theaters on Christmas Day. "I ain't afraid to die anymore, I've done it already," the 40-year-old actor proclaims.
