The unusual behavior depicted in the highly anticipated "Fifty Shades of Grey" was enough to merit an R rating, but a morality group wants an NC-17 rating because the film reportedly encouraged sexual violence.

In a report by Variety, the MPAA stamped an R rating on "Fifty Shades of Grey" not because of the raunchy scenes but for the behavior of its characters.

"The MPAA has deemed 'the strong sexual content including dialogue, some unusual behavior and graphic nudity' worthy of an R rating," it said. "Although readers of the racy book might wonder how it's possible to depict most of the action without getting closer to an NC-17 rating."

But the film is generating controversy as watchdog, Morality in Media, wants the MPAA to bump up the rating from R to NC-17 because of the sexual violence depicted by the movie.

The group said in a statement published on Entertainment Weekly that the R rating does not fully encapsulate the "violent themes" in the film.

The statement said: "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."

Morality in Media then fueled fire to the controversy as it said the MPAA should change the description of "Fifty Shades of Grey" to read: "Promotes torture as sexually gratifying, graphic nudity, encourages stalking and abuse of power, promotes female inequality, glamorizes and legitimizes violence against women."

Earlier, Jamie Dornan told GQ magazine UK quelled the controversy as he said director Sam Taylor-Johnson was very concious about making sure the sex scenes don't come off as very graphic in "Fifty Shades of Grey."

"They can't alienate an audience. You know it has to be watchable. It can't be hardcore. I wouldn't have signed up to it if it was. You've got to make something a large amount of people can go and see. It's not going to be grotesque," he said.
