For four seasons, Robin Wright has played the calculating wife of Kevin Spacey in Netflix's "House of Cards."

This week, she took a page right out of her character Claire Underwood's book. Tuesday night, Wright told an audience at a Rockefeller Foundation event how she negotiated a pay raise.

"I was looking at statistics, and Claire Underwood's character was more popular than his for a period of time in a season. So I capitalized on that moment. I was like, 'You better pay me or I'm going to go public.' And they did."

Actress Patricia Arquette raised the issue of pay inequity at last year's Oscars.

"It is our time to have wage equality once and for all, and equal rights for women in the United States of America," she said in her acceptance speech.

Jennifer Lawrence talked to Charlie Rose about making less in the film "American Hustle."

"I feel uncomfortable asking for more money. I don't want to be seem like a brat, I don't want to be seem like all of these words that are only used for women."

Wright, who has won a Golden Globe for her role in "House of Cards," says gender shouldn't determine value.

"It has to be unacceptable at this stage.

A publicist for Kevin Spacey told us today, "Kevin thinks it's amazing and well deserved! He's honored to be a part of a show that supports equal pay for women."

A spokesperson for Netflix says they have no comment regarding statements by Wright.
