The BBFC (British Board of Film Classification) is an independent body that classifies films, videos, DVDs, and some video games in the UK. They use a rating system to determine who can view different types of content. The document then describes the rating criteria for various age ratings: U (universal), PG (parental guidance), 12A, 12, 15, 18, and R18. Violence, language, sexual content, drug use, and discrimination are considered for each rating, with increasing restrictions on such content for lower age ratings. The document concludes with an example classification of "Apocalypse" as a 15 due to its threat, violence and strong language.
