Target audience of "Three's A Crowd"

We are aiming to produce our film for both young couples as well as male and females in the adult age group of 30-75. We have based this upon the use of violence between both genders in the clip of our film and the content of smoking and alcohol. Although we have decided to certify our film as a 15, it was felt that the topic may be too sensitive for a younger age group and as we have chosen the film to be based on the generic crime convention of film noir, in which murder is the dominant subgenre.
