Captain Scott's log and many of the personal effects of the explorers were loaned by The British Museum to add to the authenticity of this near-documentary.
Vaughan Williams wrote nearly 1000 bars of music for the film, much of it before filming had even started. In the event, less than half of what he wrote was actually used.
The scene where the explorers land at the Bay of Ross was specially extended in the cutting room merely to accommodate the power of Vaughan Williams' score for the sequence.
The hut where Scott and his party stay throughout the winter months before their final push to the South Pole still exists today and is a tourist attraction for those few who travel down to that part of the world. The intensely cold, dry air has preserved everything almost exactly as it was a century ago.
