The Wooden Horse
The Wooden Horse is a 1950 2nd World War film starring Leo Genn, Anthony Steel and David Tomlinson. It is based on the book by Eric Williams.
This true story, is set in Stalag Luft III, the same POW camp where the 'real' Great Escape took place. The inmates come up with an ingenious way of digging a tunnel in the middle of an open area using a vaulting horse to cover the entrance. They also had to come up with a method of disposing of the earth coming out of the tunnel. Three men did manage to escape headed for neutral Sweden.
