parent or adult guardian. Rated NC-17: Adults Only – No one 17 and under admitted. Since September 1990, the MPAA has included brief explanations of why each film received an "R" rating, allowing parents to know what type of content the film contained. For example, some films' explanations may read "Strong Brutal Violence, Pervasive Language, Some Strong Sexual Content, and Drug Material". By the early 2000s, the MPAA began applying rating explanations for PG, PG-13, and NC-17-rated films as well. Rating components Violence Depictions of violence are permitted under all ratings but must be moderated for the lower ones. Violence must be kept to a minimum in G-rated films and must not be intense in PG-rated films. Depictions of intense violence are permitted under the PG-13 rating, but violence that is both realistic and extreme or persistent will generally require at least an R rating. Language Snippets of language that go "beyond polite conversation" are permitted in G-rated films, but no stronger words are present. Profanity may be present in PG rated films, and use of one of the harsher "sexually-derived words" as an expletive will initially incur at least a PG-13 rating. More than one occurrence will usually incur an R rating as will the usage of such an expletive in a sexual context. Known as the "automatic language rule", the rule has been applied differently depending on the subject matter of the film. For example, All the President's Men (1976) received a general rating on appeal, despite multiple instances of strong language, likely because of its historic subject matter. The automatic language rule is arguably the rule that can most often be successfully appealed. The ratings board may award a PG-13 rating passed by a two-thirds majority if they believe the language is justified by the context or by the manner in which the words are used. It is sometimes claimed that films rated PG-13 are only able to use the expletive fuck once to avoid an R rating for language. There are several exceptional cases in which PG-13-rated films contain multiple occurrences of the word fuck: Adventures in Babysitting, where the word is used twice in the same scene; Antwone Fisher which has three uses; The Hip Hop Project, which has seventeen uses; and Gunner Palace, a documentary of soldiers in the Second Gulf War, which has 42 uses of the word with two used sexually.
