About little-known master of movie horror: William Castle. Largely remembered for installing electrical shocking devices in seats for added scares at his horror films, Castle reveals himself to be a fascinating, multi-dimensional man. In the 50s and 60s, he delighted moviegoers with buzzing seats, flying skeletons, luminescent ghosts and life insurance policies. Driven by a fear of failure, Castle's life was a rags-to-riches tale of a larger-than-life showman. And his role in producing and almost directing "Rosemary's Baby" only adds to his list of significant credits.
