Made in 1966, this landmark documentary by Ulster Television still stands up today as a fascinating retelling of the famous Shackleton expedition to the Antarctic on his doomed ship - Endurance.

A veteran of the tragic Scott expedition to the South Pole, Ernest Shackleton and another of the survivors of that venture, Tom Crean, were joined by a band of explorers and adventurers for another polar journey which met with disaster before they had reached the shoreline of Antarctica. Caught in ice, the ship drifted off course as the ice moved before finally being crushed and sinking. Salvaging what they could from the ship before it went down, the crew were now stranded on sea ice with no one to help them.

The story of how Shackleton led his men - all of them - to temporary safety on Elephant Island and then set off on a treacherous sailing in stormy seas to South Georgia, traversing its mountains and glaciers to bring rescue to his stranded crew, is now the stuff of legends. Here it is told through the extensive photographs the crew took along with film they shot and audio recordings years later with some of the survivors.
