On the heels of news that another Gloria Steinem biopic is in the works, FilmNation Entertainment has announced that its already greenlit film, An Uncivil War, has cast Carey Mulligan as the lead to play the pioneering feminist leader.

Last month, it was reported that June Pictures is bringing Steinem’s 2015 memoir, My Life on the Road, to the big screen, with film and Broadway veteran Julie Taymor on board to direct. Julianne Moore will be playing Steinem in that film, which has no production or release date schedule as of yet.

An Uncivil War will be directed by Dee Rees, helmer of Bessie and this month’s Mudbound, also starring Carey Mulligan. In Rees’ dive into Steinem’s trailblazing life, the story will be set in the 1970s and center on her and others’ work to ratify the Equal Rights Amendment, which ultimately failed by only getting 35 out of the required 38 state ratifications.

An Uncivil War won’t be Carey Mulligan’s first film foray delving into feminism and women’s rights. In 2015, she starred in Suffragette, about the women’s voting movement in Great Britain in the early 1900s. About her film choices, Mulligan told the Los Angeles Times in 2015, “I’m always just looking for good roles, whether it’s a really big part or a really small part.”

There’s no release date yet for An Uncivil War, but production is set to begin in March of 2018.
