Realm of Darkness - Caves of Glass

Chris Bonington and Jim Curran trace the history of K2 expeditions from 1903 to the disastrous loss of life in the summer of 1986, when 13 climbers died on K2, climbing tragedies that aggressively carved the epithet the 'savage mountain' into the public consciousness. Jim Curran was hired by the British 'Fuller’s K2' team to document their attempt on the unclimbed NW Ridge, so he was at the mountain, all summer. Inevitably, his documentary ended up drifting into a gripping narrative from the front line of the disastrous and tragic summer that killed 13 climbers on K2.

Sid Perou follows the attempt of climbing Europe's highest and most extreme rock face, the Troll Wall in Norway, using free climbing methods. The documentary features Hans Christian Dossieth, Colin Brooks, Steve Bancroft, Chris Gibb and Sid Perou.

"The first of three films by Sid Perou that trace the story of rock climbing from its simple and accessible beginnings to the exclusive world of today's dedicated rock athlete. In this episode of Rock Athlete, leading Northern climbers in action show how the increasing use of technical aids eventually led back to the primitive contest between man and rock. The film starts with film footage of the Abraham Brothers climbing the Napes Needle in 1915 and ends with Ron Fawcett soloing Tensor on Craig y Castell (Tremadog). A TV series by Sid Perou produced by the BBC."
