The Climbers.

"The Climbers" is a six-part documentary series tracing the history of mountaineering. Directed by Chris Bonington and Richard Else, it was produced by the BBC and broadcast in 1992. The series recounts the evolution of mountaineering and the traditions of climbers in Great Britain and on the European continent: the former developed a free climbing technique, while the latter used aids such as keys, pitons, and drills to ascend otherwise inaccessible routes. The program includes archive footage of the pioneers of the sport, from the emergence of free climbing as a distinct discipline in the late 1970s and 1980s to the advent of competitions.
