"Human beings simply aren't built to function at the cruising altitude of a 747," Jason Clarke says in the opening seconds of "Everest's" new trailer, foreshadowing what's to come. "Everest is, without a doubt, the most dangerous place on Earth."

Of course, foreshadowing isn't really necessary, as the action thriller is inspired by actual events: the 1996 Mount Everest disaster that left eight people dead.

Based on Jon Krakauer’s book “Into Thin Air,” Clarke, Josh Brolin, John Hawkes and Jake Gyllenhaal star in the true story of two expeditions challenged beyond their limits by one of the fiercest blizzards ever encountered as their attempt to reach the summit turns into a struggle for their lives.

Directed by Baltasar Kormákur (“2 Guns,” “Contraband”), “Everest” also features Martin Henderson, Emily Watson, Michael Kelly and Thomas M. Wright. The film opens Sept. 18.
