Christianity has had a powerful influence on every sphere of Western art, even art which on the surface might seem antithetical to the faith. This book argues that point with an analysis of the horror film genre, examining nine classics which illustrate the evolution of horror and reveal a culture haunted by fear of the unspeakable. The history and literary roots of the horror genre are also discussed. The author concludes that our innate dread of evil and the imperative of warding it off are the key mechanics of the horror experience. Films covered include Vampyr (1932), The Mummy (1932), The Thing (1951), Night of the Demon (1957), The Wicker Man (1973), The Exorcist (1973), Halloween (1978), Ringu (1998) and Pan's Labyrinth (2006).
