The film was initially a
35mm 3D
softcore "skin-flick" with minimal production values and a very basic plot. Since it was grossing extremely well in specialty "adult theaters," in 1971 Silliphant and executive producer Louis Sher decided to repackage their film into a regular R-rated, general release 3D feature film, with a more complex, conventional storyline with reduced nudity and simulated sex activity. New scenes were shot in both Los Angeles and Hawaii to "open up" the picture, including dialogue and characters on a newer passenger plane interior and cockpit. The self-imposed X rating was a draw in the early stages, attracting viewers to relatively small theaters showing the 3D film. In the last year, with the official R rating, it was possible to show the film more widely, even in 70mm 3D, in houses like the 4,300-seat
Boston Music Hall. The film ran for three years and was presented in just over 800 theaters. It outsold some higher budget movies in larger theaters. The film also played in at least 30 overseas markets. The film is also notable in that it may be the only film to be extensively re-shot, edited and updated as it played in theaters, according to Silliphant. Probably four versions of the evolving film were played over the three years that the film was in active distribution. Writer, producer, director, and 3D technologist Allan Silliphant was the younger half-brother of Academy Award-winning writer and producer
Stirling Silliphant. Co-producer and cinematographer
Chris Condon, who had founded Century Precision Optics, built innovative, relatively lightweight and portable single-strip 3D cameras. Theater owner Louis Sher was the
executive producer, and used his Art Theater Guild theaters to display the film coast to coast. Specially trained 3D technicians would be sent to each and every theater to install the special equipment, and to teach the projectionists how to keep it running. == 3D stereo technology ==
