The history of witchcraft given in the narration at the start of the movie is riddled with errors and bears very little resemblance to actual history. One of the more egregious errors is the claim that the Dark Ages followed the Middle Ages.
The film was shot in 1960 and has a copyright date of 1961 but was not released until 1964.
Libby Hall said in an interview that during her audition, she had to disrobe and dance nude for co-directors Claude Alexander and Larry Buchanan, and the Texas drive-in owner who financed the film. She had no problem with that because she was a nudist. After they cast her, she spent a full day running around the country side totally naked as the male directors and crew filmed her. Then she spent half a day skinny dipping in a large pond, and another two days filming her scenes on sets. She didn't get paid much at all, but she was excited to be part of the film.
The film is often confused with another regional movie, also titled The Naked Witch, a lost film directed by Andy Milligan in New Jersey in 1967. Claude Alexander, director of the the 1961 version, notes in his DVD commentary that he succeeded in getting the distributor, Mishkin, to change the title of that later release to The Naked Temptress.
Shot in Luckenbach, Texas.
