"Apart from being an important historic record of Captain Scott's last expedition to the Antarctic, Ninety Degrees South is also something of a pioneer film itself. Made under conditions of extreme hardship, it also shows that the documentary film, more than a decade before Flaherty, could rise to heights of poetry as well as realism. This version, benefiting from sound, narration and an introduction by Scott's surviving associate Captain Evans, was issued in the thirties. While it is unavoidably anti-climactic in a dramatic sense, since Scott's final days could only be reconstructed via stills, diagrams and diary excerpts, it is both an inspiring and poignant record, though cinematically it is Ponting's superb camerawork that is the most memorable aspect of the production."
