The BBFC (British Board of Film Classification) was established in 1912 to set censorship standards for films shown in the UK. It assigns age ratings from U to R18 based on content like violence, language, sex, and nudity. For example, 15-rated films can contain strong violence while 18-rated films contain very strong language and graphic depictions of sexual violence. The BBFC also considers UK laws like the Obscene Publications Act and Video Recordings Act when making classification decisions. One film it gave an 18 rating for graphic medical depictions was The Descent due to scenes of broken bones and stomachs being eaten.
