The treasure part of this movie is stupid, because diamonds don't emerge naturally from ground level. There is some gold finding, too - that separate escapade is done by a Nazi and a topless native woman (who is actually Latino instead of Amazonian). But I have to admit that that woman looked good. The Nazi (Pleasance) is okay, and I found myself on his side while searching for treasure in order to build a better world - (what the hell) - Though opponents to that have their way. There is a need to mention that there is a goof who is searching for oil; and he is, by far, one of the worst actors in history. The goof's girlfriend isn't too bad looking though; but miss goody two-shoes eventually shows her devious side. The main characters are the diamond getters: performed by Whitman and his two nagging companions, who travel through the jungle yelling and pointing guns at each other. Fortunately they are given the greater majority of film time, making the story passable: with the scenery and Whitman making the highlights.
