The 27 men who joined his expedition found that Ernest Shackleton was true to his word. They had drifted with the pack ice of the Weddell Sea for ten months, their ship "the Endurance" had sunk, and they were castaways in one of the most hostile environments on earth, hundreds of miles from land. And so, with his dream of becoming the first man to cross Antarctica long abandoned, Shackleton set his mind to a far greater challenge: bringing his crew safely home. Based on the detailed diaries and first-person accounts of expedition members, SHACKLETON tells the true story of their extraordinary ordeal, and the death-defying, 800 mile journey in an open boat across the worlds worst seas that made their rescue possible. Written and directed by Charles Sturridge (LONGITUDE, BRIDESHEAD REVISITED), SHACKLETON stars Kenneth Branagh (HENRY V, HAMLET) as the legendary explorer.
