Research and planning :Target audience

The target audience for my horror film trailer, film poster and film magazine is going to be teenagers above the age of 13 and below the age 20, I choose that range of target audience because there are mainly teenagers in the trailer so It wold be more appericiated and appealing to teenagers and young adults, the trailer will also include  strong language as it wont affect the teeenagers and it wont affect anybody else because they are not watching it. My target audience would or should have an interest in watching horror films and also must have a background where they are going to school, college or university and if not that then they must be working atleast part time or full time. They must like to go out with their friends and mostly enjoy hanging around with them and like going to the cinemas.
