"What we’re kind of hearing from the fans is they want it dirty... they want it as close as possible [to the book]," said producer Dana Brunetti.
As Fifty Shades filmmakers had their hands tied ratings-wise when they were asked to turn the bestselling novel into a movie for mainstream cinema audiences, they decided to come up with a different solution to please their audience.
"I always thought it would be really cool if we released the R version and then we had an NC-17 version that we released a few weeks later. Everybody could go and enjoy the R version, and then if they really wanted to see it again and get a little bit more gritty with it then have that NC-17 version out there as well. That is my idea, but the fans and the studio [Universal Pictures] will benefit from the double dip," Brunetti told Collider.
"We do not want this film to be seen as mommy porn -- we want to keep it elevated but also give the fans what they want," she added.
The Fifty Shades books tell the story of Anastasia Steele, a college student who gets swept off her feet by the S&M-obsessed, billionaire entrepreneur Christian Grey.
The first film of the trilogy -- starring Dakota Johnson, 24, as Steele and Jamie Dornan, 31, as Grey -- is set to be released in February 2015. The film began shooting in Vancouver Monday.
