"I made that phone call to her because when Ryan (Murphy) called me, I said to him, 'I have all the reasons to say yes to this, an unbelievable project, ' and I heard that he was going to do it with respect for the family - that was important for me", she explains to news show Extra.

Adding another layer of intrigue to the proceedings, or perhaps capitalizing on the publicity, on Monday afternoon, just hours before FX's planned LA premiere of the show, the network as well as producers Fox 21 responded to the Versace family with their own statement.

The Versace family has slammed a new television series on the murder of fashion giant Gianni Versace, saying it was based on nothing more than "work of fiction". Ryan Myrphy has based his interpretation of the incidents partly on Maureen Orth's 1999 book called Vulgar Favors: Andrew Cunanan, Gianni Versace, and the Largest Failed Manhunt in US History.
"Like the original "American Crime Story" series "The People vs. OJ Simpson, ' which was based on Jeffrey Toobin's nonfiction bestseller 'The Run of His Life, ' FX's follow-up 'The Assassination Of Gianni Versace" is based on Maureen Orth's heavily researched and authenticated nonfiction best-seller 'Vulgar Favors, ' which examined the true life crime spree of Andrew Cunanan". Maureen Orth is an impeccable reporter and we stand by her reporting.
The Assassination of Gianni Versace: American Crime Story premieres on 17 January. The first season of the anthology drama courtesy of Ryan Murphy was a huge hit as it followed the infamous murder trial of O.J. Simpson, and the second season will attempt to recreate that success with the story of the murder of Gianni Versace back in 1997. "Instead, in her effort to create a sensational story, she presents second-hand hearsay that is full of contradictions". But because "in making her lurid claims, she ignores contrary information provided by members of Versace's family, who lived and worked closely with him and were in the best position to know the facts of his life", the family said.
The family then condemned the TV series in its entirety for taking Orth's book as a work of nonfiction. American Crime Story also depicts Gianni as HIV positive and has the character seek treatment in one episode. In spite of the fashion house's claims, the "Glee" and "American Horror Story" producer his latest project is "a work of non-fiction obviously with docudrama elements". "The Versace family will issue no further comment on the matter".
