Director Eliot Rausch has done an excellent job bringing us the short documentary 'A World Unseen: The Revenant', introducing us to the production process of 'The Revenant', along with a commentary from the Oscar-winning director Alejandro González Iñárritu, who speaks both for the movie's production with all its ups and downs, and also for a bigger problem related to global warming and how the native American population is slowly being banished from its own lands. Leonardo DiCaprio also spoke of the tough process that he had to go through in order to entirely fit his character's demeanor and view towards the nature surrounding him. The main message of this documentary is not to give us the making insides of the movie, but to show us the bigger picture and what actually happens with our planet's nature.
