Arthur C. Clarke's Mysterious World - Season 1 Episode 4 The Missing Apeman

This episode is divided equally between considering evidence for the Bigfoot and Yeti. Interviewees for the segment on the Yeti include Don Whillans, Lord Hunt and Eric Shipton. Lengthy consideration is given to the Patterson-Gimlin film, and interviewees include Grover Krantz - who demonstrates several casts of alleged Bigfoot tracks that he feels bolsters his belief that the creature represents a relative of Gigantopithecus.
