Parsons' wife Marjorie Cameron, who performed a sex magick ritual with him and L Ron Hubbard to birth the antichrist (or whatever), appears as a "sinister woman" in Curtis Harrington's Night Tide, with Dennis Hopper. Recommended if you haven't seen it. The Parsons story is all pretty weird, not sure I want to see it dramatized on CBS, with compromises and narrative tweaks.
