Sir Douglas Mawson

Siege of the South is a 1931 Australian documentary film by Frank Hurley. It featured Douglas Mawson. It was based on footage taken on the BANZ Expedition to Antarctica in 1930–31. The film debuted in Brisbane in 1931.

Frank Hurley (1885-1962) was firmly established by 1925 as Australia's most famous photographer. An artist interested less in expressing human experiences than the grandeur of nature and the romance of exotic lands, his work was known to Australians through books, newspaper features and documentary films. His journeys began in December, 1911 when he joined Mawson's expedition to Antarctica as official photographer; his stills of the Expedition were widely published around the world and this documentary "Home of the Blizzard" was released in 1913.

The Douglas Mawson Antarctic Expedition of 1912 is considered one of the most amazing feats of endurance of all time. Although his two companions perished, Douglas Mawson survived, but how? In a bold historical experiment, scientist and adventurer Tim Jarvis is retracing the gruelling experience, with the same meagre rations, primitive clothing and equipment to uncover what happened to Mawson physically — and mentally — as a man hanging on the precipice of life and death.
