Showdown at Horseshoe Hell

Fred Beckey is the legendary American "Dirtbag" mountaineer whose name is spoken in hushed tones around campfires. This rebel climber's pioneering ascents and lifestyle form an iconic legacy that continues to inspire generations.

The true story of Joe Simpson and Simon Yates' disastrous and nearly-fatal mountain climb of 6,344m Siula Grande in the Cordillera Huayhuash in the Peruvian Andes in 1985.

Deceased but not forgotten. In 2017, Switzerland's most famous mountaineer, "Swiss Machine" Ueli Steck, fell to his death in the Himalayas when he was just 40 years old. Three close friends travel again to the Everest region where he died. His family in Emmental has to deal with premature death.

Les Etoiles de Midi is an engaging docudrama about some of the more spectacular exploits of French mountain climbers over the last several decades. In one re-enacted story, there is a wartime escape through the mountains, and in another, a daring rescue of a pair of climbers who had been missing. The actors themselves are adept at the sport of climbing, and they give the scenes an immediacy and real daring that brings the stories alive. A combination of their acrobatics and skill and the outstanding episodes in the history of French climbing creates a winning 78 minutes.

The first filmed winter ascent of the north face of the Matterhorn. To set the scene, the tragic story of Edward Whymper's first ascent is skillfully pieced together. The modern expedition, a team of three British climbers, is also plagued with epics: Eric Jones is hit by an avalanche and can only come to a dangerous stop at the edge of a 1000 foot drop. Then the worst storm ever recorded in Zermatt hits the Matterhorn. With time and weather against them, the team is forced to climb in the dark as thunderstorms rumble around them. This adventure captures the skill and courage of the climbers, their agony and tension, and the beauty of the assault on this spectacular mountain. Grand Prize at the Les Diablerets festival (Switzerland) in 1976.

After the great crossing of Fitz Roy, in Patagonia, and the Nose in less than 2 hours, in Yosemite, Alex Honnold and Tommy Caldwell embark on a new adventure: the Continental Divide Ultimate Linkup (CDUL), i.e. the chain of 17 summits of Rocky Mountain National Park, in Colorado in 36 hours. The CDUL totals 56 kilometres, 6,000 meters of elevation gain and 65 pitches, with 11 routes from 5a to 6b+ climbed in simultaneous climbing. A project by Adam Stack, Caldwell's childhood friend, who gave the iconic American rope a hard time.

In 1950, a French expedition led by Maurice Herzog went to central Nepal to conquer the highest peak (8,091 meters): Annapurna. The film is not only made of what we see, but even more of what we don't see. Its imperfections are the negative imprint of the adventure. Memory is the most faithful of films.

Record of the first ascent of Everest made without the use of oxygen equipment, made in May 1978 by Reinhold Messner and Peter Habeler. Could it be done? Would their blood vessels burst? Would they suffer brain damage leading to madness? Nobody was sure. Messner: 'I would never come here for trying Everest with oxygen. That is not a challenge for me.' A fascinating piece of history, well filmed by Leo Dickinson and Eric Jones (above the South Col Messner used a cine camera to continue the filming), featuring Messner and Habeler's thoughts. The film follows the usual sequence from Namche to Base Camp, through the Icefall, to Camps I, II and III. It also shows historical footage of the pioneering Mallory and Shipton expeditions.
