Johnny Weissmuller reprises his "Jungle Jim" character in this entertainingly dreadful drama that sees him having to face down some marauding gorillas. Except. Wait for it... Are they actually gorillas? Perhaps they are really people dressed up? Why? Well, it turns out that there is some long lost Nazi bullion hidden amongst the dense jungle of California. What's more, these creatures can throw a rock a mean distance and they have a top secret hideout too. Luckily (or not) "Jim" has two damsels to help him out on his quest to thwart this evil plan. "Barbara" (Trudy Marshall) and the local "Nyobi" (Suzanne Dalbert) but will they be enough against the menacing "Brandt" (Onslow Stevens) and his gang? It's so bad it's funny, this, with precisely no effort made to create the supposed leafy environment as these nimble furry critters clamber over the desert boulders trying to stop their heads coming off or knocking over the pot plants. There's an annoying little dog in here too, and by the denouement you almost want the baddies to win just because you know that despite their overwhelming cunning and firepower, good will prevail. The acting and writing merit no mention at all and basically it's just terrible.
