Horror films have a long history, dating back to ancient times when people would tell terrifying tales passed down through generations. Horror movies emerged as a way both to thrill audiences and tell stories about the darker side of life. Some of the top-rated horror movies include The Exorcist, Alien, Dawn of the Dead, Halloween, Psycho, A Nightmare on Elm Street, and The Shining. There are differences between horror movie subgenres, such as gory films like Hannibal, twisted psychological thrillers like The Exorcist, and jump-scare focused movies like A Nightmare on Elm Street.
