14. Ingagi (1930). This feature-length documentary was presented as the work of  “Sir Hubert Winstead,” who supposedly traveled to detail the bizarre aspects of the African ecosystem and culture – including the hitherto unknown sexual encounters between humans and gorillas. The film created headlines when it was revealed to be a blatant fraud that was created by stitching together travelogue footage with new scenes shot in a cheap Hollywood studio. Whatever it lacked in taste and class, “Ingagi” compensated with audacity – thus making it the forerunner of the modern shockumentary.
