The British Board of Film Classification (BBFC) is a non-governmental organization funded by the film industry that is responsible for classifying and censoring films in the United Kingdom. The BBFC uses a ratings system of U, PG, 12A, 15, and 18 to indicate the age suitability of a film's content such as violence, language, sex, and other themes. An R18 rating is a legally restricted classification primarily for explicit adult films that may only be viewed in licensed venues.
