The document provides classification guidelines for films rated U (Universal) and PG (Parental Guidance) by the British Board of Film Classification (BBFC). U films should be suitable for audiences aged 4+ and contain only mild violence, threat, language or horror. PG films may contain stronger content but should not unduly upset children aged 8+. Examples are given of issues examiners consider like violence, language, sex, nudity, drugs and discrimination. Sample film trailers are then assessed against the criteria, with some deemed suitable for PG and others too strong.
