The BBFC is the British Board of Film Classification, which assigns age ratings to films based on guidelines considering factors like violence, sex/nudity, language, themes and behavior portrayed. The document outlines the age rating categories from U to 18, describing the types and levels of content appropriate for each rating. It also notes the BBFC considers violence, sex, language, themes, drug use, discrimination, horror and imitable behavior when classifying a film. In an example, the document states the film "Silence Is Golden" would receive an 18 rating for strong disturbing violence, sex/nudity, racist themes, mature themes, drug use, horror and imitable behavior like torture.
