The British Board of Film Classification (BBFC) decides the certificate rating for films in the UK based on levels of sex and nudity, violence, discrimination, language, and imitable behavior. The BBFC examines films before release to assign age ratings of U, PG, 12A, 15, or 18 to ensure appropriate content for different age groups and to provide consumers information about a film's content. Higher ratings indicate the potential presence of stronger violence, sexual content, horror imagery, or other adult themes unsuitable for children.
