"Travolta has been a practitioner of Scientology since 1975, when he was given the book Dianetics while filming the movie The Devil's Rain in Durango, Mexico" Satanist Anton LaVey is credited as the film's technical advisor and appeared in the film playing a minor role, and apparently performed a "success ritual" for John Travolta. https://youtu.be/NUc65uiKOeI?t=77 Did LaVey give Travolta a copy of Dianetics to read while they were getting chummy on set?
