I think the audience for my media product would be predominately teenage, British males as all the cast members are teenagers themselves and violence generally appeals more to males as opposed to females. I don't think this film would attract an audience any older than mid-twenties as they would find the plot too predictable and the gory violence wouldn't entice them. Psychological thrillers like The Secret Window, David Koepp, (2004) would be better suited as they have adult actors and the plot is significantly more complex.
Films such as Shank, Mo Ali (2010) primarily have a cast of teenagers and thus attract a teenage audience.
In my opinion Playtime would appeal more to the male gender as it is in the slasher genre, and males are stereotypically more interested in blood, gore and graphic violence than females are.
Additionally the scream queen is a attractive, young, blonde teenager and appeals to the male gaze.
