Research & Planning: Film Poster Analysis

The medium long shot shows the main protagonist. She is the only visible character on the poster. The shot shows the back of the character so the audience do not directly see the main characters face although we can tell she is a female.
The colour of the poster has a grey tinge that gives us the sense of the genre as the darker colours show that it is a horror.
From the image and the title we can get a sense of the narrative that it is about an exorcism and the girl in the image could be Emily Rose.
The mise-en-scene element of costume is again very typical of possession films as the character is wearing a white gown just like the characters do in The Exorcist and An American Haunting. The white gown could be to show the innocence of the girls but the fact that the gowns then look dirty could show that a darker spirit is taking them over leaving them not innocent.
The location makes the poster look eerie and gives the narrative a more horror sense to it. The tagline just says 'Based on a true story' which makes the film seem more scary for the audience as they know that the events of the film are real. The audience will be teenagers mainly as they watch horror films mostly.
You can tell that it is a film poster through the cast and crew information using the steeltongs font. There is also the date of which the film was released and the website is included at the bottom of the poster.
