Realm of Darkness - The Elusive Depths of Mexico

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.

Caves of Glass is a documentary from director Sid Perou's Realm of Darkness series, focusing on the ice caves of the Austrian Tennengebirge Alps, including the Eisriesenweld and Eiskogelhöhle. It features Austrian speleologist Fritz Oedl, Belgian speleologist Guy Meauxsoone, and Ian "Tommo" White of the Northern Caving Community. First broadcast on Channel 4 on February 15, 1986, it won a Special Mention at the 5th Barcelona International Festival of Esoteric Cinema that same year.

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 last 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, Ron Fawcett puts on an epic first ascent on the famous 'Cromlech' in the Llanberis Pass of North Wales. His phrase 'Come on arms!' became a climbing catch-phrase after the film was transmitted. A TV series by Sid Perou produced by the BBC."

"The second 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, Peter Livesey, the Yorkshireman who pushed back the frontiers in the 70s relives the criticism and acclaim of his great climbs. A TV series by Sid Perou produced by the BBC."

"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."

A through trip down Simpson Pot and out of the Valley Entrance of Kingsdale Master Cave. Filmed over a dozen trips, it features cavers from the Happy Wanderers Cave and Pothole Club. It was commissioned by BBC Leeds, and was first broadcast on BBC One in October 1972.

The golden age of cave exploration falls well within living memory. Veteran caver Jim Eyres, of the British Speleological Association, relives the last great Pennines discovery - the Lancaster Hole - which allowed access to miles of river-ways, caverns and grottos beneath the western dales.
