[2] Jungle Captive features Otto Kruger, Amelita Ward, and Rondo Hatton (as a character named "Moloch").

As his assistants, Ann Forester and Don Young observe, he successfully concludes an experiment to restore life to a dead rabbit.

Stendahl later abducts Ann and transports her to his secret lab, that contains Moloch and the body of the Ape Woman.

Armed with the recorded knowledge gathered by Dr. Walters, Stendahl utilizes glandular secretions from his captive lab assistant to complete the Ape Woman's metamorphosis.

After binding Don to a chair, Stendahl and Moloch attempt to locate the missing Ape Woman.

Harrigan finds a utility bill receipt, indicating an Old Orchard Road address, paid by the biochemist.

When Don explains to Moloch that the brain transplant will result in Ann's death, the once-loyal henchman turns on his boss.

The film ends with Don and Ann being pulled over by the police and presented with a subpoena for them to appear at the magistrate's office.

Betty Bryant was signed by Universal to a term contract and was originally chosen for the role of the female lead in The Jungle Captive.

[4] From contemporary reviews, Bert McCord wrote in New York Herald Tribune that "I have come to the unalterable conviction that I just don't like motion pictures in which a fanatical doctor disinters werewolves wolf-men troglodytes and the like to bring them back to life with dire results [...] even if they were good.

[5] In The New York Times, Joelyn R. Littaure commented that Vicky Lane "plays the brainless woman with monosyllabic finesse" and "she grunts and growls as though she thought the whole business to be as stupid as it actually is".

[6] Dante stated that although Otto Kruger gave a good performance, the film "as a whole should have been better, went off the deep end too often".
