Book excerpt: "Magick" as defined by Aleister Crowley is "the Science and Art of causing Change to occur in conformity with Will." This book explores expressions of movie magick in classic occult films like Hammer's adaptation of Dennis Wheatley's The Devil Rides Out and modern occult revival movies. These films are inspired by the aesthetics of fin de siecle decadence, the symbolist writings of Villiers de l'Isle Adam, Wagnerian music drama, the Faust legend, the pseudo-science of theosophy, 1960s occult psychedelia, occult conspiracy theories and obscure aspects of animation.
