Kenneth Branagh stars as the polar explorer Ernest Shackleton in this true story of one of the 20th century's greatest adventurers. Bound for Antarctica in 1915, Shackleton's ship, the Endurance, was trapped in the pack ice of the Weddell Sea. Ten months later, the ship sank, stranding Shackleton and his crew in one of the most hostile environments on earth. Based on the detailed diaries and first-person accounts of expedition members, this tells of their extraordinary ordeal, and the death-defying, 800-mile journey in an open boat across the world's worst seas that made their rescue possible. This Special Edition version is also crammed full of fascinating extras.
