Julianna Margulies to Star in AMC's 'Dietland'

Julianna Margulies is returning to the small screen.

The multiple-Emmy winner has been tapped to star in AMC's adaptation of Sarai Walker's 2015 best-seller Dietland. Erin Darke (Good Girls Revolt) has also joined the cast.

Set against the backdrop of the beauty industry, Dietland follows Plum Kettle (Joy Nash of The Mindy Project, Twin Peaks), an obese woman who is preparing for weight-loss surgery when her world is upturned by two rival feminist factions. Caught between old ideas and radical new extremes, Plum must decide for herself what it means to be a revolutionary as the “war of the sexes” becomes literal.

Margulies will play Kitty, a wildly ambitious magazine editor whose world is thrown into chaos when a feminist terrorist organization starts targeting people in her orbit. Sucked into a terrifying news cycle, Kitty can no longer rely on her old-school media power and must instead play a whole new game of master manipulation where rules no longer apply. (Details on Darke's role were not immediately available.)

Margulies and Darke become the second and third people cast in the series, joining Nash in the drama from Marti Noxon (UnREAL, Mad Men, Girlfriends' Guide to Divorce). Dietland will premiere its 10-episode first season in 2018.

"Juliana is diabolically talented and beautiful, which makes her perfect to play our Kitty. I am genuinely honored to have the opportunity to work with her. She’s a special human and a rare actor,” Noxon said in a statement. “I can’t wait to start and for the world to get a load of this show. I am also so grateful to AMC and Skydance for supporting us and trusting the Dietland team with this provocative, wild story.”

Noxon will pen the script, executive produce and serve as showrunner. Skydance's David Ellison, Dana Goldberg and Marcy Ross will exec produce alongside Noxon's Tiny Pyro topper Maria Grasso, as well as Bonnie Curtis and Julie Lynn of Mockingbird Pictures and Jackie Hoyt. The drama is a co-production between AMC Studios and Skydance Television.

AMC landed Dietland following a multiple-network bidding war that also included Netflix, HBO and TV Land.

Margulies won Emmys for her roles on CBS' The Good Wife and NBC's ER. Her credits also include Canterbury's Law and The Sopranos. She is repped by WME. Darke is with ICM Partners.
