This movie is based on the worst disaster to ever occur in the Mount Everest region in Nepal, The 1996 Mount Everest disaster. Which refers to the events of 10–11 May 1996, when eight people were caught in a blizzard and died on Mount Everest during summit attempts. Over the entire season, 12 people died trying to reach the summit, making this the deadliest day and the deadliest year on Mount Everest. But a striking coincidence occurred when this movie was being shot in Nepal. On April 18, 2014 16 people were killed from the 2014 Mount Everest avalanche and the casualty was higher than the 1996 disaster which this movie is based on. The shooting had to be postponed and the disaster took the most lives ever taken in an Everest Disaster mostly Sherpas (all Nepalese) who were preparing ground work for the upcoming climbing season.

A consultant on the movie, survivor Lou Kasischke, published his account of the Everest tragedy in his book, After the Wind.
