Kwaheri: Vanishing Africa [1964]

This mondo-style documentary was shot by American filmmakers during a voyage to the African wilderness, and offers a glimpse of life in the vanishing primitive tribes. However, the film prefers to focus on the more exploitable elements of life among the indigenous cultures, such as a real life witch doctor performing brain surgery without anesthetic, group mating rituals, blood drinking, the slaughter of animals, human sacrifice and other examples of sex and violence in the "Dark Continent." Kwaheri was released in the United States by exploitation kingpin Kroger Babb, who billed it as "the film that stretches your eyes."
