It could have been worse. As it is, at least some of the actors are excellent, especially Christopher Lee as the only elegant mermber of the party, a dashing French hunter in Africa leading the others into the depths of the jungle to solve the mystery of Cornel Wilde's brother's mysterious death. Cornel Wilde himself appears to be a somewhat rowdy Canadian, and it takes some time for Donna Reed to find any charm in that drunken buccaneer. Leo Genn appears to be a somewhat sanctimonious missionary, but he is too good and placid to be true, and he never made the seminary. There is one more interested party in the treasure hunt, but most interesting are the natives and their behaviour, especially their music - the trumpeteer Eddie Calvert has a guest performance in this colourful safari film, where you also see all kinds of other animals, the hippopotami and the crocodiles being the most impressive seconded by giraffes, and of course there is a tame chimpanzee.
It's not a bad film, there is some excitement and charm to it, the jungle environments are terrific with their hidden dangers, and it's not too long. It's an entertainment with a fresh and nice dialogue, that at least should leave you happy and content afterwards when the curtain has fallen on the exotic drama of how an African sect could be manipulated out of the jungle.
