This document outlines the British Board of Film Classification (BBFC) rating system for films and videos in the United Kingdom. It describes the criteria for ratings of U, PG, 12A, 15, and 18. A U film is suitable for all age groups but may upset young children. A PG film needs parental guidance for scenes that may upset children under 8. A 12A film requires an adult to accompany any child under 12 to view it at the cinema. A 15 rating means no one under 15 can view the film at the cinema or rent/buy the video. An 18 rating means a film is only for adult viewers and can contain very strong themes such as violence, language, sexual content, and discrimination.
