Everest Trailer: Jake Gyllenhaal's New Movie Will Give You Goosebumps

Of all the movies based on true stories to hit theaters in 2015, Everest is perhaps the most heartbreaking. Starring Jake Gyllenhaal, Jason Clarke, and Keira Knightley, the movie tells the tale of the 1996 blizzard on Mount Everest that claimed the lives of eight hikers. The visuals are so spectacular that you'll be shivering even if you're watching on a small screen. The movie is based on the book Left For Dead, written by one of the survivors of the tragedy. Knowing how this story ends will make this movie, opening on Sept. 18, even harder to watch. Take a look at the trailer below.
