Target Audience

The target audience for my film will be 15+ but i am really aiming it only up to the age of around middle ages as as i have done my research i have found that older people do not watch film trailers and do not tend to watch new films as much, also the theme of the film is not really aimed at older people. It will be aimed at teenagers mainly, so the rest of my research will be based on teenagers and what they enjoy and expect from films as my survey monkey was aimed at a broad amount of people of all ages.
