The BBFC is a British non-profit organization established in 1912 to provide age classifications for films and videos shown in UK cinemas and sold on DVDs/videos. They assign ratings of U, PG, 12A, 12, 15, and 18 based on the level of violence, language, sexual content and other factors. The document discusses the criteria for each rating in detail. For their new film project, the document's author determines that a 15 rating is most suitable due to scenes of strong violence, the depiction of a deteriorating psychological state, and frequent strong language.
