Horror has a close generic relationship with comedy, as both genres attempt to elicit bodily reactions, from instinctual gasps and reflexive chuckles to involuntary shutting of eyes and uncontrollable laughter. Horror comedy movies that are hilarious and terrifying operate by leaning into the similarities of the two body-genres. Often, the source of comedy in such instances is the absurdity of the human body and its various responses to extreme stimuli. So, the very act that would horrify a viewer in a somber tone becomes comical in a comedy.
