Back to Sid's filmography: This was the first film credited to Sid Perou, and featured an actual cave rescue. Originally, Sid was to be the sound recordist but the designated cameraman found the caving environment difficult to work in, and Sid was co-opted. The opportunity for filming came on Sunday 12 October, 1967 when the Cave Rescue Organisation were called out after Eric Luckhurst fell down the final pitch in Sunset Pot. Unfortunately, Eric died on the way out, having suffered a punctured lung. Cavers in the film include Pete Gray, Gordon Batty, Sid Perou, Reg Hainsworth, Jim Leach, Harold Burgess, Brian Boardman, and Roger Sutcliffe. Caves featured include Alum Pot and Long Churn as well as Sunset Pot. The film was first broadcast on BBC One in 1968. In 1977 it won the Reportage category at the new Festival International du Film de Spéléologie at La Chapelle-en-Vercors.
