Bwana Devil is a 1952 film written and directed by Arch Oboler and starring Robert Stack, Barbara Britton, Nigel Bruce, Ramsay Hill, and Paul McVey. Based on the true story of the Tsavo maneaters, the story takes place in British East Africa. Thousands of workers are employed building a railway over the continent when they are attacked by two hungry lions. Jack Hayward (Stack) and Dr. Angus Ross (Bruce) attempt to stop them, but are unsuccessful, as many of their workers are killed. Britain then sends three game hunters to their rescue, but when the lions end up eating the game hunters, Hayward is forced to take matters into his own hands. Will he be able to succeed where others have failed? Bwana Devil was one of the first films to ever show in color 3-D. Critics, however, were largely were unimpressed with both the story and the usage of 3-D.
