Our target audience for the thriller film would primarily be teenagers and young adults aged 15-30, especially white British males who enjoy crime and suspense genres. A secondary audience could include older adults like our example character Steve, a 37-year-old single male teacher who enjoys thriller/horror films and has free time to go to the cinema. We would aim for a BBFC 15 rating to appeal to a wide teenage and adult audience, rather than limiting it to only adults with an 18 rating.
