格雷的五十道陰影
The "Fifty Shades of Grey" trilogy has inspired many parodies in print, in film, online, and on stage. In November 2012, Universal Studios attempted to prevent the release of "Fifty Shades of Grey: A XXX Adaptation", a pornographic film based on the novel, citing copyright and trademark infringement. Smash Pictures, the porn producer, later responded to the lawsuit with a counterclaim that "much or all" of the "Fifty Shades" material was placed in the public domain in its original "Twilight"-based form, but later capitulated and stopped production of their film.
