The document discusses key events in the classification of horror movies in the UK from 1991 to the present. It notes that in 1993, Child's Play 3 was withdrawn due to links to the Jamie Bulger murder case. In 1996, a film was rejected for a certificate due to featuring a child killer, following the Bulger case. Natural Born Killers was initially banned in 1997 over potential links to killings but was later released uncut. Classification decisions have considered depictions of violence, drug use, sexual content, and the potential effects on audiences, especially children and teenagers.
