The Stewardesses is a 1969 American 3D softcore comedy film written and directed by Allan Silliphant (credited onscreen as Alf Silliman Jr.) and starring Christina Hart, Monica Gayle, Paula Erickson and Donna Stanley.

Originally self-rated "X", in 1971 the film was re-edited with newly shot scenes to receive an "R" rating from the Motion Picture Association of America to qualify for a wide general release.

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.

Co-producer and cinematographer Chris Condon, who had founded Century Precision Optics, built innovative, relatively lightweight and portable single-strip 3D cameras.

The film was uniquely marketed in that it never used a promotional trailer but with many billboards, radio spots, and always an impressive "road show" treatment on the marquee of the theater.

In the early days of video, Caballero Control Corporation released a re-edited version of The Stewardesses on VHS and Betamax tape formats, which are now out of print.

In creating this XXX version, Caballero edited hardcore insert shots into the film and re-released it, with the tagline "From 3D to 3XXX" on the tape cover.
