Produced by Reuven Frank and narrated by Piers Anderton and first aired on 10 December 1962, the NBC documentary The Tunnel follows a group of West Berlin students determined to help people flee communist East Berlin.
Featuring footage shot inside the tunnel under the Berlin wall, the programme offers a unique insight into the remarkable efforts some were willing to go to in order to secure the freedom of others.
The tunnel stretched 120 to 140 metres below the border from Schönholzer Strasse 7 to Bernauer Strasse 78.
As the film points out the intention was to free many more East Germans but the tunnel flooded after 29 people had used it to cross from East to West.
The documentary and the story it depicts also inspired the film Der Tunnel (2001) and the documentary Der Tunnel: Die Wahre Geschichte (1999).
