Jungle Jim is a 1948 American adventure film directed by William Berke and starring Johnny Weissmuller.

[2] After attempting in vain to save a man from being mauled to death by a leopard, Jungle Jim discovers a vial containing an unknown potion.

He takes it to district commissioner Marsden, who identifies it as being from the hidden temple of Zimbalu and brings in Dr. Hilary Parker to head up an expedition with Jim as her guide.

The potion isn't the polio vaccine Hilary hoped it would be, but she expresses a willingness to work again with Jim in future adventures in the jungle.

"[8] The New York Times said Weissmuller played "a fat, but physically fearless, and miraculously clever jungle guide... foiling witch doctors and white villains much as he's done of old" but added "it's not quite the same old Johnny.

"[9] Variety said "while filling its purpose satisfactorily for the kiddie field producers might have attracted a broader market had they given it more adult intent.
