Kenneth Anger was inspired to make the film after attending a Halloween party where the theme was "Come as your Madness".
The film was very popular - especially in its 1966 revision - with the counterculture movement and was watched by many under the influence of LSD and magic mushrooms.
Inspired by Joris-Karl Huysmans novel "À rebours" (1884).
Anaïs Nin was originally to portray the Scarlet Woman, but when Kenneth Anger befriended Marjorie Cameron and learned that she considered herself to be the physical incarnation of the Thelemic deity Babalon and had been Jack Parson's Scarlet Woman she was "demoted" to the role of Astarte. Supposedly not without jealousy.
Gasper Noé's Lux Æterna was particularly inspired by this film.
