Steinem worked as a Playboy Bunny in the New York City chain while writing an expose about the treatment of women in Hugh Hefner's clubs.
Now Steinem is urging audiences to avoid the forthcoming TV series, which stars Amber Heard and is based on the first Playboy Club in Chicago, Illinois.
The political activist tells Reuters, "It was the tackiest place on earth. I expect that The Playboy Club (TV show) will be a net minus and I hope people boycott it. It's just not telling the truth about the era...
"I just know that over the years, women have called me and told me horror stories of what they experienced at the Playboy Club and at the Playboy Mansion."
Steinem's account of the Playboy Clubs was made into the 1985 movie A Bunny's Tale, starring Kirstie Alley as Steinem.
In 1963, celebrated feminist/author/editor Gloria Steinem -- then a struggling journalist -- decided to do a piece on the newly opened Playboy Club in the Big Apple for Show Magazine and gamely joined other new recruits for training as a Playboy Bunny. The fluff piece later turned up in her best-selling book "Outrageous Acts and Everday Rebellions" and two decades later was expanded into this lightheared TV movie with Kirstie Alley portraying the Steinem of the Bunny brigade. An Emmy Award nomination went to the battery of film sound editors.
