The document discusses the British Board of Film Classification (BBFC) system for rating films in the UK. It outlines the criteria for different rating categories from U to 18, including what levels of language, sex, violence and other content are permissible. The author then analyzes how their short film opening scene would likely be rated PG or 12A due to implied violence and hints at bullying, but that if expanded into a feature film dealing with teenage issues like sex, drugs and escalating violence, it would merit a 15 rating.
