The Wooden Horse (1950) VHS

Adapted from the classic novel 'The Tunnel Escape' by Eric Williams, this is the story of British POWs trying to escape from a Nazi camp through a tunnel underneath their exercise horse. As their huts are too far from the boundary, one of the officers decides to start a daily gymnastics session, close to the boundary, in order to make digging a tunnel a lot easier and less likely to arouse suspicion.
