Here is an actual case of a porn parody of "50 shades of grey" :
Universal Settles ‘Fifty Shades’ Porn Parody Lawsuit
Smash Pictures won't argue that their film is a protected spoof nor that the original books are not copyrighted; Instead, the company has decided to pay up.
For those looking forward to a lawsuit over a porn version of Fifty Shades of Grey, here’s a downer.
Universal Studios has completed a settlement with the makers of Fifty Shades of Grey: A XXX Adaptation. According to a court filing, Smash Pictures will make a payment of a confidential sum to make the lawsuit go away and also will consent to a permanent injunction that will prohibit the distribution of the XXX Adaptation.
Universal and its Focus Features division spent $5 million in March 2012 to acquire rights to make Fifty Shades of Grey movies based upon E L James‘ series of novels about a literature student who meets a young billionaire entrepreneur and the erotic passions and bondage they have together.
Smash Pictures and James Lane (aka Jim Powers) thought the story was a natural adult movie, so they made one. Smash exec Stuart Wall told a newspaper, “Since they are going to make a mainstream [film] of the books too, dabbling in the adult world, we’re choosing to go with a XXX adaption which will stay very true to the book and its S&M-themed romance.”
Slapping a “parody” tag onto the title wasn’t enough to keep Universal from protecting its rights. Along with Fifty Shades Ltd., the copyright owner of the original material, a lawsuit was filed in November that called the XXX Adaptation a “
willful attempt to capitalize on the reputation of the book.”
