Invasion of the Saucer Men (also known as Invasion of the Hell Creatures, working title - Spacemen Saturday Night) is a 1957 sci-fi horror and comedy film starring Steven Terrell and Gloria Castillo and personally produced by James H. Nicholson for his American International Pictures (AIP). The screenplay by Robert J Gurney Jr and Al Martin was based on the 1955 short story "The Cosmic Frame" by Paul W. Fairman. The film was released as a double feature with I Was a Teenage Werewolf.
A spaceship lands in the woods. A teenage couple, Johnny Carter (Steven Terrell) and Joan Haydon (Gloria Castillo), driving down lover's lane without headlights, accidentally run down one of the aliens. Joe Gruen (Frank Gorshin) a drunken opportunist, comes across the alien's corpse. He plans to keep the body in his fridge, but after failing to convince his buddy Artie Burns (Lyn Osborn) to help him retrieve the dead alien's body, he returns alone.
The aliens arrive and kill Joe by injecting alcohol into his veins via their hypodermic fingernails. Having reported their close encounter to the police, Johnny and Joan return with the Sheriff, only to find Joe's body in place of the alien.
The police plan to charge them with manslaughter. Meanwhile the dead alien's hand detaches itself, grows an eye, and runs amok. The military, following a UFO report, are soon involved. They surround the alien's spaceship, but in the end it is the teenagers who defeat the aliens when they discover that they cannot stand the glare from their car headlights.
Movie rights to the short story were purchased through the Ackerman Science Fiction Agency.
Special effects technician Paul Blaisdell, who did the alien make-up, recalled that the film was originally intended as a serious feature but gradually fell into a comedy. The entire film takes place in the period of one night with 98% shot on a studio soundstage.
In 1965 Larry Buchanan cheaply remade the film in color for AIP-TV as The Eye Creatures, a made-for-television movie.
The Lillingtons had a song entitled "Invasion of the Saucermen" on their Death by Television album.
