The LA Times has an interesting, long story about a gorilla movie that pre-dates King Kong by three years, called Ingagi. Many scenes are similar to King Kong, but it contains even more racist and lurid human-ape sexual innuendo than the more famous movie that followed.
The movie purports that not only are tribal women sacrificed to the "Ingagi," but some otherwise barren women mate with the gorillas by choice in order to conceive. At the climax of the film, a naked woman emerges from the bush to mourn her dead gorilla lover. But "Ingagi's" most offensive moment shows a topless black woman cradling a baby adorned with patches of glued-on fur, described as "a strange-looking child, seemingly more ape than human."
