some adult material. An R-rated motion picture may include adult themes, adult activity, hard language, intense or
persistent violence, sexually-oriented nudity, drug abuse or other elements, so that parents are counseled to take
this rating very seriously. Children under 17 are not allowed to attend R-rated motion pictures unaccompanied by
a parent or adult guardian. Parents are strongly urged to find out more about R-rated motion pictures in
determining their suitability for their children. Generally, it is not appropriate for parents to bring their young
children with them to R-rated motion pictures.
NC-17 — No One 17 and Under Admitted.
An NC-17 rated
motion picture is one that, in the view of the Rating Board, most parents would consider patently too adult for their
children 17 and under. No children will be admitted. NC-17 does not mean "obscene" or "pornographic" in the
common or legal meaning of those words, and should not be construed as a negative judgment in any sense. The
rating simply signals that the content is appropriate only for an adult audience. An NC-17 rating can be based on
violence, sex, aberrational behavior, drug abuse or any other element that most parents would consider too
strong and therefore off-limits for viewing by their children
X – Matured Audience Only.
(non MPAA rating) Only adults are allowed to watch these motion pictures.
