Faith horror refers to a significant outcropping of mid-1960s and 1970s films and adaptative novels that depict non-Christian communities of evil doers and their activities. Before this period, the classical horror villain was ultimately ineffectual. The demonic monster was an isolated, lone individual easily vanquished by an altruistic Christian protagonist. Alternatively, the villain in faith horror is organized into identity-affirming, likeminded religious congregations that successfully overcome protagonists. Faith horror was a cinematic trend that depicted Satanism, witchcraft and paganism during a cultural deliberation over the "Death of God," which debated the legitimacy of alternative spiritualities and the value of alliance to any faith at all. Covering popular works like Rosemary's Baby, The Wicker Man and The Omen, this book regards these films and their literary sources in relation to this historical moment, providing new ways of understanding both the period and the faith horror movement more generally.
