Mute: Target Audience

For our film Mute the group and I have decided on a suitable target audience:

Breifly, to establish the gender; Because our film theme is horror/thriller a predominantly male audience would like to view this. This is because men are conventionally seen as more 'risk takers' than the more conventionally 'vulnerable' women. However, the secondary audience may be women as one of the main characters is a woman, so they can empathise along with her character.
  The age group of which I believe is suitable for our opening sequence is 18-30 as it is of a mature theme. Mature themes such as: mature language, torture, violence and rape. As the film is based in the United Kingdom the ethnicity of majority of the characters are Caucasian and British, therefore the audience of the film would also predominantly be White, British. The social class for this film would be C2 Working Class because it is not very sophisticated or formal so it wouldn't apply to anyone above the Working Class. The sexuality would most likely be Straight as there is no representations of homo/bisexuals in the film. The demographics of the audience would be explorers, as I find our opening sequence has something very different to offer. The type of people to watch our film would be a male and female couple late at night (as it does include the aforementioned mature scenes).
