With the exception of CAPTIVE GIRL, this may be the worst film in the entire "Jungle Jim" series. This film is below average even for a Jungle Jim movie, and the average was pretty low to begin with. The plot is a rehash of the previous film, JUNGLE JIM (1948); bad guys from the outside want to pillage a lost city in the jungle. The city is supposed to be in some far off remote region of Africa, but judging from the film, its about an hours walk from a populated port town. This film is loaded with all kinds of plot contrivances and elements that don't ring true, even for a Jungle Jim movie. The only thing of interest is the exciting ( and pretty bizarre) final confrontation with the bad guys.
