The BBFC (British Board of Film Classification) decides the age ratings for films shown in British cinemas and on video in order to protect different audiences. Films are rated as Universal (U), Parental Guidance (PG), 12A/12, 15, 18, or R18. The ratings provide guidelines about what types of content, such as violence, language, sexual content and drug use, are appropriate for different age groups. The BBFC aims to balance children's safe viewing with creative freedom for filmmakers.
