"I don't want to just glorify violence. It should be disgusting and horrible and it should make you feel sick. My movies are weird, and you can't make weird, 500-million-dollar films" -Rob Zombie
Horror films have been dismissed as violent, low budget B movies and exploitation films. Nonetheless, all the major studios and many respected directors, including Alfred Hitchcock, Roman Polanski, Stanley Kubrick, John Carpenter, William Friedkin, Richard Donner, and Francis Ford Coppola have made forays into the genre. Serious critics have analyzed horror films through the prisms of genre theory and the auteur theory. Some horror films incorporate elements of other genres such as science fiction, fantasy, mockumentary, black comedy, and thrillers.
