Fifty Shades of GreyThere is a lot of sex in "Fifty Shades of Grey," the book. There won't be quite as much in "Fifty Shades of Grey," the movie.

Though the idea of an NC-17 version floated around, the finished movie is rated R for "strong sexual content" and "unusual behavior." And the script was even toned down from early drafts.

"There was a sense there was way too much sex," director Sam Taylor-Johnson told Variety. "The story, of course, is of equal importance. We tried to balance the narrative correctly, so one doesn't feel like it's drowning the other."

One infamous sex scene that stars Jamie Dornan and Dakota Johnson won't be portraying? Let's just say it involves a tampon. Including it "was never even discussed," Taylor-Johnson revealed.

Though author E.L. James fought to include as many original details from her book as possible, she ultimately gave her thumbs up to the movie - even without all of the sex scenes.

"'Fifty Shades of Grey' is first and foremost a romantic love story," she said, "and sex is only a part of that."
