From analysing the diagram above, the female audience is shown to be more interested and watch more romance films and that action appeals to the male audience more. Some of the trailers I have watched consist of these age ratings:
THE TAKING OF PELHAM 123 15
DONNIE DARKO 15
PANIC ROOM 15
THE SHINING 15
ENEMY OF THE STATE 15
WHAT LIES BENEATH 15
These trailers I have watched so far are aimed for the older audience, the teenagers and the young adults, I personally think that as being at the age of 17 with many experiences, horrors films is a massive jump of film styles you would see, for example till we are 15 we watch more Disney films, which are aimed for young people, horror films are the next stage of genre that anyone can experience.
I think from the thriller audiences, in my own film i would do something mixed with a thriller genre, like a thriller romance to attract a wider audience.
