National Geography’s engrossing new documentary on Disney+, Endurance, tracks the 2022 Antarctic expedition led by celebrated maritime archaeologist Mensun Bound. The expedition, aboard the Agulhas II, is trying to locate the shipwrecked Endurance, the vessel abandoned by Captain Ernest Shackleton and his crew in October 2015. Shackleton had set out in November 1914 to reclaim Britain’s reputation as the world’s greatest explorer, after the Norwegian Roald Amundsen had beaten British hero Captain Scott to the South Pole in 1911. Undeterred, Shackleton insisted a bigger prize would be had by crossing Antarctica from sea to sea, via the pole.
