Celebrities urge all to fight for women

A number of high-profile entertainers - including Oprah Winfrey, Mary J. Blige, Charlize Theron and Meryl Streep - have signed an open letter calling on world leaders to fight for gender equality across the globe.

The letter released on March 6 states that some 62 million girls around the world are denied the right to education, 500 million women can't read and 155 countries have laws that discriminate against women.

"Nowhere on earth do women have as many opportunities as men. Nowhere," the letter says. 

"The fight for gender equality is global."

Signers also include Tina Fey, Robert Redford, Shonda Rhimes, Ashley Judd, Amy Poehler, Colin Farrell, Danai Gurira, Connie Britton, Elton John, Patricia Arquette, Muhammed Ali, Sheryl Sandberg and Sean Parker. The push is organized by the ONE Campaign, co-founded by Irish rocker Bono to end extreme poverty and disease.
 
"We still living in a time period where the most impoverished and disadvantaged people in the world are, without question, women and girls," said Gurira, the playwright of the Broadway show "Eclipsed," in an interview. 

"The light and the potential of women and girls in the world today is being blocked."

The letter comes a few days before International Women's Day, which is today. It calls on leaders to help girls and women fight HIV and malnutrition and support female economic empowerment.

Gurira, who also plays a sword-wielding zombie assassin on AMC's "The Walking Dead," has long been an advocate for women.In Photos: Construction of Istanbul's third suspension bridge nears end In Photos: Two militants killed in operation after attack on Istanbul police stationIn Photos: Turkish police use tear gas, water cannon to disperse protestors...
