In horror films typical conventions are used to potentially scare the audience, using the right conventions to suit the film genre can seperate a good horror to a bad by creating the right suspence and drawing the audience in. There are many textual elements in which create the horror genre to be distinct, these include: the setting, technical code, iconography, narrative structure, and characters in the film.
The most obvious convention I feel is the iconography which signifies to the audience that they are watching a horror genre. Objects used in the mise-en-scene would include: blood, masks, and icons of the supernatural such as ghosts, moving objects, bladed weapons and references to religion like crucifixes, gravestones and pagan symbols. All of these connote the audience to feel uncomfortable as these aren’t seen regularly in everyday life for example ghosts, vampires and monsters or objects in which lead to or signify death, gravestones, axes and knives.
Anthropologist Claude Levi-Strauss studied binary opposites in fims in which I have related to horror films. These are used to convey the loss of child innocence as dolls are iconic to childhood and purity which are binary oppositions- evil/innocence.
Horror can be signified by other sources of iconography by other visible signifiers such as the dark black and red colours used in which have obvious connotations of: darkness, evil, blood and danger. The use of black has been used through the low key/high contrast lighting, emphasising shadows such as the moon, creating the lighting to be more expressive and non-naturalistic, connoting hell and primitive instincts. This is because when we distinguish black objects we instantly imply death as death is promoted as a dark thing.The majority of horrors are set at night time/ out of hour places which convey a characters innocence, as these are when a person feels alone and most venerable.

Audiences also expect the story to be set in small communities or rural isolated places as this offers the audience to feel unsafe in a community in which could harbour a secret, for example: a village may hold a curse. The commonly used houses are quite large and have several floors, easy hiding places which portray more mystery and suspense for the audience.
On the technical approach in horror films the ambient sounds of footsteps and heartbeats high in the sound mix, and camera work is made to be very expressive, meaning the camera angles used are more creative and can even portray a specific mood, as this is all used to try frighten the audience by creating suspense. From changes in the depth of field, watching hidden movement in the back and foreground, to high and low canted angles that both create the audience to feel disorientated and uncomfortable, as they are looking onto the situation in an imbalanced prospective. Extreme close-ups and point of view shots are frequently used, to allow the audience to identify with the characters expressions, influencing us to share their emotions. By the use of these shots this makes the audience feel we are looking onto the situation in the monsters eyes, invading their personal space and experiencing their situation. The editing of shots creates suspense and tension by the pace of long shots which are quickly cut to close ups becomes unsettling, as usually smooth transitions with mid shots have been used.

The main narrative character roles and narrative structure conventions in horror films have a key protagonist, often the victim who becomes the hero. This is usually “the final” girl. The final girl tends to be virginal and is terrorised. She is also usually the pure, slightly masculine girl who’s friends with a group of stupid immoral teenagers.

Anthologist theorist Vladimir prop a Russian critic had a theory in which there are 8 character roles in which are: the hero, the villain, the donor (the provider of an object with some magic property, the helper (who aids the hero), the princess, her father (who rewards the hero, the dispatcher (usually sends the hero away) and the false hero. I feel this theory works for most horrors, yet more than one character can fit into a specific role, as some characters with mental issues change from villains to heroes or by being made psychotic by early events. The return of the repressed is often used in horrors as previous experiences of characters are put into their unconscious, until an object or something iconic, forces them to remember the previous incident. This is used in horror as these previous experiences tend to be bad memories in which they try to forget, until being forced by something else to remember and be re-visited by the past.
Children are also used in horrors to frighten the audience as children are so venerable and precious, as they don’t have a lot of experience in what is right and wrong, therefore easily influenced or killed quickly.
Other media theorists have different ideas on the stereotypical narrative structures Tzvetan Todorov believes classic Hollywood structures evolve in horror films. For example the film starts of with normality moves on to the enigma then finding a pathway to resolution resulting with closure, or a hero finds an agent of change in which goes on a quest to resolution resulting with closure. Some films use false closures so left ambiguous to create a deeper meaning in the plot, or left to enable a sequel.
All of these key conventions make up the genre of horror, as this is what the audience expect to, and want to see, creating them to be scared.
