Explorer Lewis Cotlow (Savage Splendor) filmed his travels through Central and South America for this 1951 pseudo-ethnographic study of its inhabitants, ultimately landing on the feared, blowgun-wielding Jivaro people and their predilection for decapitating enemies and making tchochkes of the severed head. Despite claims of witnessing the Jivaro method of reducing the noggin of a nemesis to the size of an orange, Cotlow and crew managed to return home with hat sizes intact. In 1954 Cotlow wrote and published "Amazon Headhunters," an account of his experiences with the Jivaro.
