Drafting and Planning: How horror is portrayed in movie posters?

As the film, I am making is going to be a horror genre, I decided to dedicate this post to looking at the different generic conventions of a horror film. My film trailer has the name winters revenge and the conventions that I could use in my poster are:

• The main image could be either a person or an object as a main focus of the poster
• A variety of different shot types can be used on a horror poster from long shots, medium shots, extreme close ups
• Uncommon lighting and/or dark lighting
• Credits at the bottom of the page
• Film Title
• Some films mention previous films from the same director or production company
• Tagline
• Cinema Release Date
• "Coming Soon" or "In Cinemas soon"
• Social media links
• Website for the movie

The poltergeist has a main image of a clown which is
used to emphasis the creepiness and scariness of the film.
This also has a social media link which says
'#WHATAREYOUAFRAIDOF'

This poster uses unnatural lightning as it draws attention to the girl in the middle of the poster. It shows a normal setting like a bedroom but has an unusual element of the light. Also this Paranormal activity poster has a tagline that says 'For the first time you will see the activity' which is a short and memorable slogan.

Posters such as scream and Annabelle use extreme close ups to emphasis more detail of the antagonist like on the Annabelle poster you can see tears of blood which suggest an evil nature to the doll which links to the narrative of the film

This poster uses dark lightning to emphasis
the horror and mystery in the poster
