Tenzing Making-of Featurette Reveals the Dangers of Filming on Everest

Recreating one of mountaineering's greatest achievements demanded more than convincing visual effects. In a new behind-the-scenes featurette for Tenzing, Apple TV reveals how director Jennifer Peedom and her cast endured genuine mountain conditions to bring the historic Everest expedition to the screen.

The film tells the story of Tenzing Norgay (Genden Phuntsok), who became one of the first two people to reach Mount Everest's summit alongside New Zealand mountaineer Edmund Hillary (Tom Hiddleston) on 29 May 1953.

Rather than relying extensively on digital backdrops, Peedom chose to film in real mountain environments across Nepal and New Zealand.

The making-of video reveals the extraordinary logistical challenges involved. One sequence required approximately 400 extras, 70 animals and 40 principal cast members, while filming on glaciers exposed the production to dangerous crevasses, freezing temperatures and unpredictable weather.

Crew members describe powerful winds exceeding 100 km/h, unexpected overnight stays in mountain accommodation and the constant pressure of completing scenes before deteriorating visibility made helicopter evacuations necessary.

Beyond the physical challenges, the featurette explores the filmmakers' commitment to representing Sherpa culture authentically. Members of Norgay's family discuss their involvement in the production and their trust in Peedom's approach to telling his story.

The cast also includes Willem Dafoe, Caitríona Balfe and Thinley Lhamo.

Tenzing has been streaming globally on Apple TV since 16 October 2026.

The behind-the-scenes footage demonstrates how the production's determination to capture real landscapes helped transform a historical achievement into an unusually immersive cinematic experience.
