It's a cheap exploitation of jungle movies mixed with mad science. Really crazy stuff about proving evolution through blood from apes....or, something like that. Cool gorilla suit, mixed with live action. A film oddity of the early 1930s. Probably trying to ride the coat tails of KING KONG...disastrously. And, throw in FRANKENSTEIN too as the name of the scientist is....Boris Borodoff! Wait till you hear the sound effects of the "gorilla's" voice!
