Hoyt Curtin's original music score--consisting solely of guitar, bass and piano--was recycled by director Edward D. Wood Jr. for his film Jail Bait (1954).
The film was originally begun by Herbert Tevos as "Lost Women of Zarpa", but a variety of factors--funds running out and neither the producers nor the cast being able to get along with Tevos--resulted in the production being shut down and then abandoned. A few years later Ron Ormond bought the film, shot some new footage and released it as "Mesa of Lost Women".
In Catalan, "aranya" means "spider."
The name "Tarantella" for the dancer played by Tandra Quinn is an in-joke. "Tarantella" is both the Italian word for "tarantula" and the name of an Italian dance that is supposed to make the person doing it look like he or she has just been bitten by a tarantula.
The character of Dr. Aranya and the spider people were added by Ron Ormond. Herbert Tevos' original story began with Masterson--who was merely a "schizophrenic homicidal maniac"--at the cantina, where the dancer played by Tandra Quinn was just a murder victim. The rest of the story is much the same as was seen in the film minus the various scenes involving the women and dwarfs watching the crash survivors. The film ended when Mexican authorities responded to the flare Phillips fired off and landed on the mesa, whereupon Phillips, Doreen, and Van Croft were rescued and the love triangle was resolved when Doreen chose Phillips over Van Croft.
