is a 1931 exploitation film
. It purports to be a documentary of Sir Hubert Winstead of London on an expedition to Africa, and it concerns a tribe of gorilla-worshiping women encountered by the explorer. It was produced by Congo Pictures and distributed by RKO Radio Pictures
. While marketed under the pretense of an ethnographic
film, the premise was fabricated, leading the Motion Picture Producers and Distributors Association
to retract any involvement with the film.
The film trades heavily on the suggestion of sex between a woman and a gorilla. Its success motivated RKO to invest in the film King Kong (1933).
