Robin Wright Threatened to "Go Public" Unless She Got Equal Pay as House of Cards Co-Star Kevin Spacey

The actress added that if she were denied, she would go public about it

Score 1 for equal rights, thanks to Claire Underwood, who held all the cards.

Robin Wright says she demanded to paid the same amount as co-star Kevin Spacey for her work on the Netflix series House of Cards—and even said that if she were denied her request, she would go public about it. The 50-year-old actress made her comments during a discussion about human rights and equality at the Rockefeller Foundation in New York City Tuesday.

"I was like, 'I want to be paid the same as Kevin,'" The Huffington Post quoted Wright as saying. "It was the perfect paradigm. There are very few films or TV shows where the male, the patriarch, and the matriarch are equal. And they are in House of Cards."

"I was looking at the statistics and Claire Underwood's character was more popular than [Frank's] for a period of time," she said. "So I capitalized on it. I was like, 'You better pay me or I'm going to go public.' And they did."

House of Cards showrunners and Netflix have not commented. In addition to her leading acting role, Wright also serves as an executive producer on the political drama series and has also directed several episodes.

Women working full-time in the United States only make about 79 percent of what men earn, according to the U.S. Department of Labor.

"It's not about learning, it's about unlearning," Wright said, according to the Rockefeller Foundation, adding that mothers face "significant natural barriers" in the workplace.

Patricia Arquette had famously spoken out about wage equality in her acceptance speech for Best Supporting Actress at the 2015 Oscars, earning a standing ovation and a particularly enthusiastic response from Meryl Streep, and continued to advocate for the issue publicly since then.

Later that year, Jennifer Lawrence made headlines with an op-ed titled, "Why Do I Make Less Than My Male Co-Stars," published in Lena Dunham's Lenny Letter newsletter. Forbes had dubbed Lawrence the world's highest-paid actress, with an estimated $52 million in earnings. The actress wrote she was paid less than "the lucky people with dicks" in American Hustle, which earned her an Oscar nomination.

Gwyneth Paltrow also got candid about the gender pay gap in Hollywood. The actress, who raked in approximately $9 million in 2015 and is the 12th highest paid actress, , according to Forbes, weighed in on the ''disparity'' between her salary and that of her Iron Man co-star Robert Downey Jr., who earned $80 million in 2015 and was named the world's highest paid actor for the past three years.
