Horror films use certain themes, props, settings, and character archetypes to invoke fear and thrill audiences. Common themes include hauntings, religion, good vs. evil, and monsters. Props like knives and masks are often used to denote the genre. Settings tend to be graveyards, abandoned buildings, cabins, and haunted houses at night to create tension. Character archetypes include the final girl protagonist, the unlikely hero, the antagonist villain, and the sex appeal character who is often the first to die.
