DiCaprio took a more serious approach after taking the stage to a standing ovation during the 2016 Academy Awards. "Making The Revenant was about man's relationship to the natural world," the environmental activist told the crowd, using the opportunity to discuss climate change.

"Climate change is real, it is the most urgent threat facing our species," he explained. "Let us not take this planet for granted. I do not take tonight for granted."
