In 2018, Isaac Kappy exposed several celebrities, actors, producers and other Hollywood people, as being involved in such cults as exposed in this documentary. A few months later, Kappy was found dead under mysterious circumstances; this, after he had shared a video of himself saying that he was not suicidal and if something happened to him it was Hollywood coming after him, in retaliation.
In 2023, Sound of Freedom (2023), a movie addressing the same topic and starring Jim Caviezel, finally came out, after years of it being censored in the form of legal roadblocks put in place by Hollywood, to prevent its release.
More than 85 years prior, The Black Cat (1934) showcased such a satanic cult, although the movie takes place in Hungary. Boris Karloff subsequently shot to fame, while Bela Lugosi---refusing to comply with Hollywood's inane demands to maintain his former A-Lister status--- slowly sinking into obscurity, relinquished to doing movies at Poverty Row. Interestingly enough, every single film Karloff ever made involved some sort of bondage scene or bondage elements "seen", sometimes including children, such as in Son of Frankenstein (where, according to Donny Donnegan, Karloff conveniently dropped him on the hard concrete floor, so that his five-year-old self had to be strapped, with metal wires, to the quinquagenarian's chest) and The Island Monster (1954) from where a notoriously compromising photo, of Karloff with a 5-year-old little girl, surfaced in 2018.
