The British Board of Film Classification (BBFC) is responsible for classifying films, videos, DVDs, and some video games in the UK. It provides guidelines for what types of content are appropriate at different rating levels. For example, a 'U' rating is suitable for children aged 4 and over and should not include horror, threat, violence or illegal drugs. A '15' rating means no one under 15 can see the film in a cinema; it can contain strong language, violence, and threat but should not dwell on pain or injury details. The filmmaker's piece was rated '15' due to scenes of violence, threat, and imitable dangerous behavior over two minutes including a death and threatened hostage.
