Target audience and notional BBFC rating.

The age range for our film is ideally 15-24, we chose this because from looking at the BBFC classification regulations it's a 15. As it features small amounts of swearing and in the rest of the film we would include a sex or two.

The Brittish Board of FIlm Classificaion must give every film a certificate before it's screened in cinemas to protect the people watching. 

Wiki:The British Board of Film Classification (BBFC), originally British Board of Film Censors, is a non-governmental organisation, funded by the film industry and responsible for the national classification of films within the United Kingdom.  It has a statutory requirement to classify videos, DVDs and some video games under the Video Recordings Act 2010.
