Bwana Devil is a 1952 American adventure B movie written, directed, and produced by Arch Oboler, and starring Robert Stack, Barbara Britton, and Nigel Bruce. Bwana Devil is based on the true story of the Tsavo maneaters and filmed with the Natural Vision 3D system. The film is notable for sparking the first 3D film craze in the motion picture industry, as well as for being the first feature-length 3D film in color and the first 3D sound feature in English.

The advertising tagline was: "The Miracle of the Age!!! A LION in your lap! A LOVER in your arms!"

Plot

The film is set in British East Africa in the early 20th century. Thousands of workers are building the Uganda Railway, Africa's first railroad, and intense heat and sickness make it a formidable task. Two men in charge of the mission are Bob Hayward and Dr. Angus McLean. A pair of man-eating lions are on the loose and completely disrupt the undertaking. Hayward desperately attempts to overcome the situation, but the slaughter continues.

Bwana Devil

Britain sends three big-game hunters to kill the lions. With them comes Bob's wife. After the game hunters are killed by the lions, Bob sets out once and for all to kill them. A grim battle between Bob and the lions endangers both Bob and his wife. Bob kills the lions and proves that he is not a weakling.

Cast

Historic background

The plot was based on a well-known historical event, that of the Tsavo maneaters, in which many workers building the Uganda Railway were killed by lions. These incidents were also the basis for the book The Man-eaters of Tsavo (1907), the story of the events as written by Lt. Col. J. H. Patterson, the British engineer who killed the animals. The story was also the basis for the film The Ghost and the Darkness (1996) with Michael Douglas and Val Kilmer.

Natural Vision 3D Film Process

By 1951 film attendance had fallen dramatically from 90 million in 1948 to 46 million. Television was seen as the culprit and Hollywood was looking for a way to lure audiences back. Cinerama had premiered on September 30, 1952, at the Broadway Theater in New York and was a success there, but its bulky and expensive three-projector system and huge curved screen were impractical, if not impossible, to duplicate in any but the largest theaters.

Former screenwriter Milton Gunzburg and his brother Julian thought they had a solution with their Natural Vision 3D film process. They shopped it around Hollywood. 20th Century Fox was focusing on the introduction of CinemaScope and had no interest in another new process. Both Columbia and Paramount passed it up.

Only John Arnold, who headed the Metro-Goldwyn-Mayer camera department, was impressed enough to convince MGM to take an option on it, but they quickly let the option lapse. Milton Gunzburg turned his focus to independent producers and demonstrated Natural Vision to Arch Oboler, producer and writer of the popular Lights Out radio show. Oboler was impressed enough to option it for his next film project.

Oboler said he had overheard Joseph Biroc and the camera crew talking about 3D while filming The Twonky and Oboler became interested.

Production

Oboler announced the project in March 1952. He said it would be called The Lions of Gulu and would include footage shot in Africa several years beforehand. Filming was to start in May. It was always going to be in Natural Vision.

Howard Duff and Hope Miller were the first stars signed.

Eventually Duff and Miller dropped out and were replaced by Robert Stack and Barbara Britton. The title of Oboler's film was changed to Bwana Devil in June 1952. (Oboler already announced he would make a second film in the format, Spear in the Sand with Lisa Howard.)

The film was shot in the San Fernando Valley.

The Paramount Ranch, now located in The Santa Monica Mountains National Recreation Area, sat in for an African savanna. There is now a hiking trail in the area named "The Bwana Trail" to denote the locations used in Bwana Devil. Authentic African footage shot by Arch Oboler in 1948 (in 2D) was incorporated into the film. Ansco Color film was used, instead of the more expensive and cumbersome Technicolor process.

Lloyd Nolan appeared in a prologue for the film.

The film was given Code approval in two dimension but not in three dimension due to a kissing scene. Eventually approval was given.

Release

The film premiered under the banner of "Arch Oboler Productions" on Wednesday, November 26, 1952, with a twin engagement at the Hollywood Paramount Theatre and the Paramount Theatre in downtown Los Angeles. It opened to the public the following day.
