Bosses at the Motion Picture Association of America (Mpaa) have been criticised by an anti-pornography watchdog for giving Jamie Dornan's upcoming erotic drama Fifty Shades Of Grey an R rating.

Last week (ends11Jan15), bosses at the Mpaa gave the saucy film, about a student who embarks on a kinky relationship with businessman Christian Grey, an R rating, which means those aged under 17 can see it with an adult.

They granted the film the classification citing "strong sexual content including dialogue, some unusual behavior and graphic nudity", and members of watchdog group Morality in Media have blasted the description because it does not inform parents of the extreme sexual nature of the movie.

They write, "What the term 'unusual' does not account for is the coercion, sexual violence, female inequality, and Bdsm themes from which the entire Fifty Shades plot is based... Such a vague evaluation puts viewers at risk, sending the message that humiliation is pleasurable and that torture should be sexually gratifying.

"We'd like to change the Mpaa rating for Fifty Shades of Grey to read: 'Promotes torture as sexually gratifying, graphic nudity, encourages stalking and abuse of power, promotes female inequality, glamorises and legitimises violence against women.'"

The group also wants the film to be given the tougher Nc-17 rating, which prohibits anybody under 17 seeing the movie, ahead of its U.S. release in February (15).
