Margo Martindale, John Slattery, Jeanne Tripplehorn, Tracey Ullman, Melanie Lynskey, Ari Graynor and Kayli Carter have also joined the cast of the limited series 'Mrs. America.'

FX is adding a who's-who of top talent to join Cate Blanchett in Mrs. America.

Uzo Aduba, Rose Byrne, Kayli Carter, Ari Graynor, Melanie Lynskey, James Marsden, Margo Martindale, Sarah Paulson, John Slattery, Jeanne Tripplehorn and Tracey Ullman have boarded the nine-episode limited series, which focuses on efforts to ratify the Equal Rights Amendment.

The project looks at the unexpected backlash led by a conservative woman named Phyllis Schlafly (Blanchett). Through the eyes of the women of that era — Schlafly and second-wave feminists Gloria Steinem (Byrne), Betty Friedan (Ullman), Shirley Chisholm (Aduba), Bella Abzug (Martindale) and Jill Ruckelshaus (not yet cast) — the series will explore how one of the toughest battlegrounds in the culture wars of the 1970s helped give rise to the Moral Majority and forever shifted our political landscape.

Anna Boden and Ryan Fleck, who most recently co-wrote and directed Captain Marvel, will helm the first two episodes of the series and executive produce. Mrs. America hails from Emmy-winning writer Dahvi Waller (Mad Men), who will pen the script, exec produce and serve as showrunner. Two-time Oscar nominee Stacey Sher will also exec produce, alongside Blanchett and Coco Francini.

Here are the details on the impressive cast, courtesy of FX:
