The BBFC guidelines establish age ratings and content restrictions for films and videos distributed in the UK. The ratings include U for universal, PG for parental guidance, 12A/12 for ages 12 and over, 15 for ages 15 and over, 18 for adults only, and R18 for pornographic material restricted to licensed sex shops. The BBFC aims to protect children from harmful content while respecting adult freedom of choice. Ratings consider themes, language, sex, violence and drug use, with older age ratings allowing more explicit depictions but still prohibiting gory or abusive content.
