Inspired by real events it follows DiCaprio's character through deep snow and graphically depicted ordeals including battles with Native Americans and the near-fatal mauling by a bear.
Inarritu filmed it chronologically over seven months in the snows and bitter cold of Canada, in weather which often sunk to minus 25 degrees, using only natural light, which sometimes meant filming for only two hours a day.
Relaxing outside the Santa Monica screening room, a bearded DiCaprio said: "It was a test of all our endurance. I think we all knew going into it we were embarking on an adventure that would test everything about us---and it absolutely did. The weather was so excruciatingly cold"
Some members of the crew left, saying it had been by far the worst experience of their careers--"a living hell" one called it.
Inarritu concedes: "We were in very tough conditions in very unfriendly territories. Everybody was frozen, the equipment was breaking and to get the camera from one place to another was a nightmare."
The Revenant will be released briefly on Christmas Day in order to qualify for Oscar contention and already it is being tipped to win awards for both the director and star.
