Don't expect the effects of a big Hollywood budget...this was shot on a shoestring and the cast is entirely unknown. Despite this, there are no belly-laughs but it is quite humorous. Believe it or not, it's better than some of the other unauthorized Tarzan films made on a bigger budget in other countries. Tarzun looks to be barely 21 and very boyish. It's amusing that whenever he walks his loincloth nearly slides off as if he needs suspenders. The horny ape who chases Jayne and manages to score won't give up even after Tarzun stabs it in the groin. The horny thing eventually gets Meena, too. Tarzun's jungle doctoring on Jayne is equaled only by Meena's doctoring of Tarzun's gonads after he hits a tree full frontal and arrives at her doorstep moaning and holding his crotch. If you are offended by nudity and unabashed sexual acts being depicted, stay away. In just over an hour length, "Tarzun in the Valley of Lust" manages to keep you chuckling if not laughing.
