He played a minor on-screen role and served as technical advisor for the 1975 film The Devil's Rain and served as host and narrator for Nick Bougas' 1989 mondo film Death Scenes.Historian of Satanism Gareth J. Medway described LaVey as a "born showman", with anthropologist Jean La Fontaine describing him as a "colourful figure of considerable personal magnetism". The academic scholars of Satanism Per Faxneld and Jesper Aagaard Petersen described LaVey as "the most iconic figure in the Satanic milieu". LaVey was labeled many things by journalists, religious detractors, and Satanists alike, including "The Father of Satanism", the "St. Paul of Satanism", "The Black Pope", and the "evilest man in the world".

Jack Thomas Chick (April 13, 1924 – October 23, 2016) was an American cartoonist and publisher, best known for his fundamentalist Christian "Chick tracts". He expressed his perspective on a variety of issues through sequential-art morality plays.
Many of his tracts accused Roman Catholics, Freemasons, Muslims, and many other groups of murder and conspiracies. His comics have been described by Robert Ito, in Los Angeles magazine, as "equal parts hate literature and fire-and-brimstone sermonizing".Chick's views have been spread mostly through the tracts and, more recently, online. His company, Chick Publications, says it has sold over 750 million tracts, comic books, videos, books, and posters designed to promote Evangelical Protestantism from a Christian fundamentalist perspective. They have been translated into more than 100 languages.Chick was an Independent Baptist who followed a dispensationalist view of the End Times. He was a believer in the King James Only movement, which posits that every English translation of the Bible more recent than 1611 promotes heresy or immorality.
