Jake Gyllenhaal & Josh Brolin Suffered Altitude Sickness As They Prepared For ‘Everest’
Brolin told Outside magazine, “I remember in rehearsals, I was like, ‘I don’t feel right, do you feel right?'” But Gyllenhaal admits the experience was helpful because it made him realize how the brain works at altitude, where the air is thin and survival is key. He tells the publication, “They (the real-life characters) were having to make moral choices at 28,000 feet, an area where the body does not function.” The film is loosely based on author Jon Krakauer’s account of two rival Mount Everest expeditions, led by mountain gear outfit store bosses Fischer and Rob Hall. Both teams, featuring experts and amateur climbers, were left stranded in a storm at 28,000 feet and eight people lost their lives in a day. The film will open the Venice International Film Festival in Italy on September 2, 2015.
