It's looking like the 50 Shades of Grey movie will be just as sexually graphic as the book!

Lest you thought we would get a watered-down version of the popular mom-read on the big screen, the movie's screenwriter Kelly Marcel is hinting that fans can expect something less PG-13 and more late night Cinemax. "We are 100 percent going there. It will be rated NC-17. It will be raunchy," she said.

An NC-17 rating means that no one under the age of 17 can get in to the movie, even with a parent or guardian. And most of these movies basically amount to porn with murder. The last NC-17 movie to be released by a major studio was Showgirls, and we all know how well that turned out...

But according to producer Dana Brunetti and Universal Studios, the NC-17 rating is news to everyone else. “A screenplay has not yet been written, a rating has not been designated, and we have no further comment,” said a the studio rep, according to The Hollywood Reporter. Ratings are obviously assigned after the film has been shot and edited, and so it's the director and studio, not the screenwriter, who decide how explicit the film's content will ultimately be.

If we had to guess, we'd bet that Universal will hedge its bets and go for the R rating to ensure a wider audience. Though if ever there was a time to see if a major studio release can make big bucks with an NC-17, 50 Shades of Grey is it...

Do you think an NC-17 rating is good or bad for the movie?
