With more and more big budget films relying heavily on CG, studios have been taking care to release behind-the-scenes featurettes and interviews promoting real locations and sets. A recent promo for Mission: Impossible – Rogue Nation focused on Tom Cruise performing his own dangerous stunts, while details on Alejandro Gonzalez Iñárritu’s The Revenant reveal a film that was shot as naturally and realistically (and excruciating for some) as possible. In a similar vein, a new promo for Everest highlights the intense conditions endured by the cast and crew on set.

The use of real locations and sets, particularly those with severe conditions, has become something of a badge of honor for filmmakers, which is certainly awesome in light of the overabundance of CGI in mainstream filmmaking. With that in mind, Universal and the cast and crew of Everest show off the extreme conditions they endured while filming on location in the snowy, dangerous mountains of Nepal.

Baltasar Kormakur (2 Guns) directed the film from a screenplay by Mark Medoff (Children of a Lesser God) and Simon Beaufoy (Slumdog Millionaire). The film tells the harrowing true story of two groups of climbers embarking on a dangerous expedition up Mount Everest.

The excellent ensemble cast includes Jake Gyllenhaal, Jason Clarke, Josh Brolin, John Hawkes, Robin Wright and Keira Knightley. Everest hits theaters and IMAX on September 18.
