The British Board of Film Classification (BBFC) rates films in the UK by assigning them an age rating. They have 7 rating symbols ranging from Universal to adult works suitable only for licensed premises. The BBFC classifies films according to guidelines that consider factors like discriminatory content, drug use, imitable behaviors, language, nudity, sexual activity, violence and frightening scenes. Their goal is to ensure films are suitable for the assigned age group and to protect children from harmful content. Different countries may have different film rating systems and laws to abide by.
