The document describes the different age rating certificates used in the UK for films. A U certificate means anyone of any age can view the film, while a PG may contain mild language or violence disturbing for young children. A 12A means those under 12 need an adult, while a 12 is prohibited for under-12s. A 15 bars those under 15, and an 18 anyone under 18, with increasing restrictions on content like violence, language, sex and nudity. An R18 is for pornographic films restricted to licensed adult cinemas for over-18s only. The document rates their own film a 15 due to intense horror scenes, violence and language that may offend those under 15.
