The document discusses British film classification and ratings. It explains the ratings system used by the British Board of Film Classification (BBFC) which ranges from U to 18. Films rated 12A, 12, 15 and 18 can contain increasing levels of violence, language, sexual content and other mature themes. The document then analyzes similar thriller films to determine that its own film sequence, which includes strong language, drug use, abuse and bloody violence, would merit a 15 rating in the UK. Feedback from teachers and classmates supported this rating. The filmmakers conducted audience research through a questionnaire to help target their 15-year-old audience.
