A Nazi war criminal named Franz,hidden in the jungles of Africa,is running guns to the presumably hostile natives.The governments of the world send an inept band of agents,poorly disguised as a reverend and four nuns,to investigate."Tarzan and the Mystery of Jungle" is a perfect example of turkey cinema.The acting is laughable,the fight scenes are horrible and there is no nudity.Richard Yesteran steals the show as Tarzan and his yell is wonderful.The film is pretty tough to find,but if you like laughably bad cinema give it a look.Recommended.
