potential target auidence:

I began my research by looking at official reports from the British Film Institute, the screen shot below shows what different age categories enjoy watching in terms of film genre.

The table above shows that both male and female spectators below the age of 35 enjoy watching Horror films, whereas as spectators of both genders above the age of 35 do not enjoy watching horror films as much.
Due to this statistic I would draw the conclusion that my target audience would be from 16-25
The lowest being 16 due to the influence of horror and gore within the film and would not be suitable for anyone younger.
25 being the oldest because statistics show that the most common age of people who go to the cinema to watch horror films are between the age of 16-24.
