The rating system for films

PG Parental Guidance – General viewing, but some scenes may be unsuitable for young children Unaccompanied children of any age may watch. A ‘PG’ film should not disturb a child aged around eight or older. However, parents are advised to consider whether the content may upset younger or more sensitive children.
Discriminatory language or behaviour is unlikely to be acceptable unless clearly disapproved of or in an educational or historical context. Discrimination by a character with which children can readily identify is unlikely to be acceptable.
References to illegal drugs or drug misuse must be innocuous or carry a suitable anti-drug message.
Frightening sequences should not be prolonged or intense. Fantasy settings may be a mitigating factor.
No detail of potentially dangerous behaviour which young children are likely to copy. No glamorisation of realistic or easily accessible weapons.Mild bad language only.Natural nudity, with no sexual context.Sexual activity may be implied, but should be discreet and infrequent. Mild sex references and innuendo only.Where more serious issues are featured (for example, domestic violence) nothing in their treatment should condone unacceptable behaviour.Moderate violence, without detail, may be allowed, if justified by its context (for example, history, comedy or fantasy).
