The document discusses the BBFC (British Board of Film Classification) and their role in rating films for release in UK cinemas. The BBFC examines each film to determine its age rating based on content like themes, violence, and language. Films are rated U, PG, 12A, 15, or 18 based on increasing levels of mature content. The document provides examples of films like Attack the Block and Dawn of the Dead that received 15 and 18 ratings respectively due to strong language and graphic violence. It also notes that films aimed at children like Coraline can contain some scary moments despite a PG rating.
