I have just obtained a copy of Cannibal Attack and rather enjoyed it.
In this one, a ship load of cobalt is ambushed by people disguised as crocodiles and they try to pinch it. Jungle Jim (Johnny Weismuller using his own name) and some others investigate this and face several dangers in the process including crocodiles, a big eagle and a leopard, which Jim kills. He and somebody else are then caught by unfriendly natives and are fed to the crocodiles, but are rescued at the end and the thieves are caught or killed.
Joining Weismuller in the cast are Judy Walsh and David Bruce.
I obtained this movie from the same source as I get the Bomba movies. This is worth watching if you get the chance as it is quite rare. Great fun.
Rating: 3 stars out of 5.
