This was one of a group of remakes that was shot in 16mm and color and used to pad out one of American International's television syndication packages.
Because of the movie's bargain basement budget, Buchanan could not afford anything as ornately bizarre and iconic as Paul Blaisdell's design for the original She Creature, so his Gill Monster costume, created by Dallas advertising executive turned makeup effects artist Jack Bennett, consisted of an ill-fitting and only slightly modified green rubber wetsuit and a cheap-looking fanged and finned, ping pong ball-eyed fish mask which Buchanan later reused as a briefly seen cave-dwelling dinosaur in his 1969 film 'It's Alive!'.
Actor Aron Kincaid made the film as part of an out-of-court settlement with AIP. He filmed for two weeks to meet his contractual obligations then left to return home. Buchanan was upset as he still had three days of scenes for Kincaid to do. He accompanied him in the cab to the airport, taping the rest of his dialog in the back seat.[
In addition to playing one of the She Creature's victims, Texas Rockabilly singer Scotty McKay (a.k.a. Max K. Libscomb, 1940-1971) performed three songs in the movie including Here Comes Batman, his tribute to the popular TV series.
