NBC’s upcoming "Playboy Club," which has been under fire over its subject matter since the show was announced, has gained another detractor: famed feminist Gloria Steinem, who is calling for a boycott of the show, reports Reuters.

Steinem worked undercover in 1963 as a Playboy bunny in New York City’s Playboy Club and wrote an expose about the conditions faced by the women who worked there.

"Clearly ‘The Playboy Club’ is not going to be accurate. It was the tackiest place on earth. It was not glamorous at all," Steinem told Reuters. She added that she feels AMC’s "Mad Men," also set in the 1960s, is a "net plus" because it depicts the era with "some realism.”

"I expect that ‘The Playboy Club’ will be a net minus and I hope people boycott it. It’s just not telling the truth about the era," Steinem said. "When I was working there and writing the expose, one of the things they had to change because of my expose was that they required all the bunnies, who were just waitresses, to have an internal exam and a test for venereal disease," she said.

We reported recently on Steinem’s undercover work and her 1963 article “I Was a Playboy Bunny” in an Open Mic piece by Hillary Atkin on the upcoming NBC show, which you can read here.
