I thought the movie “From Hell to Borneo“, released in 1964, is the oldest movie with the name “Borneo” in the title.
That is until I came across information about the existence of a movie much older than Hell, called “The Beast of Borneo”.
It tells the story of a mad scientist named “Boris Borodoff” who conducts strange experiments involving men and apes.
EZTakes says the film “contains the most laughable ape ‘growl’ ever committed to film.” The film is available for download in selected country and region, here.
