The document outlines the different film rating classifications used in the UK by the British Board of Film Classification (BBFC). U means all ages are admitted and there is nothing unsuitable for children. PG means all ages are admitted but some scenes may be unsuitable for young children and may contain mild language, sex, drugs or moderate violence. 12A means those under 12 must be accompanied by an adult and films can contain mature themes, discrimination, soft drugs, moderate language and violence, sex references and nudity. 15 and 18 ratings restrict admission and content to older age groups and allow increasingly stronger language, violence, sex and nudity.
