The horror movies scare, thrill, and scream people.
According to Wikipedia, Horror films are movies that strive to elicit the emotions of fear, horror and terror from viewers. Their plots frequently involve themes of death, the supernatural or mental illness. Many horror movies also include a central villain.
Early horror movies are largely based on classic literature of the gothic/horror genre, such as Dracula, Frankenstein, The Wolf Man, Phantom of the Opera and Dr. Jekyll and Mr. Hyde.
More recent horror films, in contrast, often draw inspiration from the insecurities of life after World War II, giving rise to the three distinct, but related, sub-genres: the horror-of-personality Psycho film, the horror-of-armageddon Invasion of the Body Snatchers film, and the horror-of-the-demonic The Exorcist film.
