The document outlines the content guidelines for films rated 15 and 18 by the British Board of Film Classification (BBFC). For a 15 rating, some drug use, threat, dangerous behavior, mild language, and nudity are allowed but sexual content must be limited and not dwelled on. An 18 rating means no one under 18 can view the film. Exceptions to the 18 guidelines include films that breach criminal law, pose risks to viewers, or contain unjustified explicit sexual content.
