Son of Ingagi is a 1940 American black horror monster movie directed by Richard C. Kahn. It was the first science fiction horror film to feature an all-black cast. It was written by Spencer Williams based on his own short story, House of Horror. Although the film’s title appears to suggest that it is a sequel to the 1930 movie Ingagi, it is not. (The latter is an exploitation film in the guise of an ethnographic film in which purported African women are given over to gorillas as sex slaves.)

Son of Ingagi is about Elanor and Bob Lindsay inheriting the house of Doctor Helen Jackson who had just returned from her trip to Africa. Jackson also had returned with a missing link monster named N’Gina as well as African gold. When N’Gina drinks the doctor’s potion, it puts him into a rage that makes him murder Dr. Jackson. The Lindsay family inherits Jackson’s house where they soon find the presence of the monster.
