Climb to the top of the world's deadliest mountain in the first trailer for Universal Pictures true-life thriller Everest. Jake Gyllenhaal and Keira Knightley lead in all-star cast in this chilling look at one of the most dangerous expeditions ever attempted. We also have a bunch of new photos and a look at the teaser poster, in case you missed it when it debuted earlier in the year.

Inspired by the incredible events surrounding an attempt to reach the summit of the world's highest mountain, Everest documents the awe-inspiring journey of two different expeditions challenged beyond their limits by one of the fiercest snowstorms ever encountered by mankind. Their mettle tested by the harshest elements found on the planet, the climbers will face nearly impossible obstacles as a lifelong obsession becomes a breathtaking struggle for survival.
