My audience

My opening sequence is thriller and hence, I should be targeting an older age group.However, my cast is young and I am trying to show the life of a young teenage girl being stalked so it allows me to attract the younger population.  As this is a serious issue which can happen to any age children, I want to be able to spread awareness to all age groups but keeping in mind the thriller element I will target age 12+. I don't want to restrict any body from watching this movie as it is inspirational how a 17 year old girl fights such a threatening issue on her own.
