What in contemporary cinema is a horror film and what is a science fiction movie? "Blade Runner" (1982) is as much film noir as science fiction, and it is a literary adaptation. The latest remake of "The Mummy" (1999) is more an effects fantasy or action/adventure than straightforward horror. Whatever your viewpoint, the best of these movies have generated cults and imitations and the worst have a wonderfully perverse appeal all of their own. This new volume in the "Sight and Sound "readers series provides a varied and diverse overview of trends that have shaped sci-fi/horror in the last decade. It explores how recent films like "The Fight Club" and "The Truman Show" have impinged on more traditional territory and have tested the limits of conventional understandings of these most central of genres. The book engages with a host of topics that have emerged over the last decade: vampire movies, body horror, the nuclear threat, childhood terror, artificial worlds, and postmodern horror. It includes fresh looks at classics such as "Rosemary's Baby, Psycho, Halloween, Nosferatu, " and "Blade Runner," as well as 90s highlights the "Scream "series, "I Know What You Did Last Summer, Strange Days Existenz, " and "Cube."
