There are 5 main aspects that make up the form of a horror film: theme, settings and location, characters, narrative, and iconography. Common horror film themes include supernatural, gothic, slasher, and psychological horror. Typical settings are old, abandoned locations like houses, schools, forests and countryside. Characters of all ages and genders can be used depending in the theme. Narratives usually start with disequilibrium, have a circular structure, and end with the resolution of fear. Iconography like blood, gothic styles, and low lighting help identify the horror genre.
