The BBFC provides film ratings in the UK to indicate the age suitability of films. Films are rated on a scale from U to 18 based on the level of violence, sexual content, drug use, and language. The ratings aim to help protect children and sensitive viewers from content they may find inappropriate. Each rating level has specific criteria that films must meet around these content areas to qualify for that rating. The BBFC reviews all films released in the UK and assigns an appropriate rating to help inform viewers and enforce age restrictions for viewing and purchasing films.
