A period drama set in Panama in 1850, "Jungle of Fear" is an odd piece of material for "Kraft Suspense Theatre", usually dealing with contemporary mysteries.
The script by John McGreevey is vaguely (a great stretch in fact) resembling the format of a "Casablanca" -an international setting of intrigue, where foreigners are anxious to get away and travel to California to join the Gold Rush there.
Robert Fuller stars, styled comfortably in Western movie costuming, in the Bogie role owning a saloon who controls most of what goes on in a small port town. Ann Blyth plays a Chinese woman (see other IMDb reviews for reactions of viewers who can't get beyond the obsolete Hollywood casting of stars in other-races roles) on the run from the Chinese government, whose predicament forces out-for-himself Fuller to decide to do a noble deed for a change. Robert Loggia with a full head of hair (or rug) is the local constabulary role (a la Claude Rains) and Harold Sakata, fresh from OddJob in "Goldfinger" is also on hand for fight scenes.
The script is by John McGreevey, a prolific tv writer who worked with Fuller on many episodes of "Wagon Train".
Scene stealer is an obscure German beauty Susanne Cramer (an Elke Sommer type) who sings and provides Fuller romance working in his saloon. Her IMDb bio is typically cryptic and badly researched -yet intriguing -I would be interested in her real life story.
