One of the year's most anticipated films, Fifty Shades of Grey, is just one month away and after being rated 'R', by the MPAA, people are eager to find out why.

'Fifty Shades of Grey' Is One Month Away

Just last week, the Motion Picture Association of America announced that the film's 'R' rating is a result of "strong sexual content, including dialogue usual behavior and graphic nudity and for language."

It's no secret that the E. L. James' sexy best selling novel was a lot of shades of sexy, but heartthrob Jamie Dornan announced that there would be no full frontal views in the film.

It's clear that film will not be as kinky as the novels, but what's with the 'unusual behavior' part?

Fifty Shades producer Dana Brunetti spoke with USA Today at Sunday night's Golden Globe Awards, and he opened up on his feelings on the MPAA decision.

During the Golden Globes red carpet interview Brunetti said they were shooting for an 'R' rating but he's a little confused about the 'unusual behavior' portion of the MPAA decision.

"I'm thinking they saw a different movie than me," the producer said. "I had a good laugh when I saw that. So many people e-mailed me about that before I had even seen it. And they were like, 'What does unusual mean?' It's pretty unusual to me."

Even some unusual behavior won't stop fans from seeing their favorite movie debut on the big screen.

Get ready fans, the movie of the year is on its way. Fifty Shades of Grey hit theaters nation wide on Friday, Feb. 13th
