The Revenant is a 2015 American epic western adventure film based in part of Michael Punke's The Revenant; A Novel of Revenge...inspired by experiences of frontiersman and fur trapper Hugh Glass, Set in 1823 Montana and Dakota..Both Leonardo and Hardy worked together on Inception and I presume the director must have seen something...which has turned out to be a great success. This was a project that was initially cut for Directors, Park Chan-Wook and John Hillcoat with Samuel L.Jackson and Christian Bale as main actors respectively.
The budget for this film was $135 Million and initial development of this project started in August 2001 amidst some controversies as to who to produce, fund, act and all that but... Award winning Mexican Director, Alejandro Gonzalez Inarritu is taking the glory at the end of the day because history might repeat itself in the life of this man who was responsible for the success of Birdman or (The Unexpected Virtue of Ignorance), A comedy film that won Best Picture, Best Director and Best Original Screenplay at the last Academy Awards.
Revenant was shot in 12 different locations and 3 different countries; Argentina, Canada and the United States. It may interest you to know that Alejandro insisted that computer-generated imagery not be used to enhance the film stating ''If we ended up in greenscreen with coffee and everybody having a good time, everybody will be happy, but most likely the film will be a piece of shit''. Hence, It was shot with natural lighting amidst bad weather conditions and some crew members giving up on the project..It was a very challenging time for the director who had 30-40 difficult sequences while shooting, he also had to go in and out of frozen rivers and sleeping in animal carcasses...At the end of the day, the glory has been written for the world to see and celebrate.
