MGM+ Orders ‘The American Heiress’ Starring Julianna Margulies

If you've been enjoying all the wealth, romance, and society drama of The Gilded Age, MGM+ has another period series you might want to add to your watchlist. The network has officially ordered The American Heiress, an eight-episode romantic comedy starring Emmy winner Julianna Margulies, and we're already expecting plenty of expensive gowns, questionable marriages, and wealthy people making everybody else's lives difficult.

Based on Daisy Goodwin's bestselling novel of the same name, the series will take viewers back to 1893, when marrying into British aristocracy was practically a competitive sport for wealthy American families. Margulies will portray Isabella Cash, a determined mother who takes her daughter across the Atlantic in pursuit of something all their American money apparently can't buy: a British title. And you thought modern dating was exhausting.

What's ‘The American Heiress’ About?

The story follows Cora Cash, a wealthy young American woman who reluctantly accompanies her formidable mother to England in search of a suitable husband. Cora believes she's already in love with Teddy, an American artist, but her plans take an unexpected turn after a horseback riding accident leaves her recovering at Lulworth Castle.

The castle happens to belong to the 12th Duke of Wareham, and suddenly Cora finds herself navigating a world where appearances, family names, and social standing seem to matter more than actual happiness. Meanwhile, Isabella has her own challenges when she encounters the Double Duchess, an aristocratic woman who knows the rules of British high society better than just about anybody. Let's just say Isabella might be used to getting her way back home, but England is about to give her a little competition. Between ambitious mothers, romantic complications, and people who seem more interested in titles than actual relationships, there's plenty of room for things to get messy.

Julianna Margulies Leads the New Series

Margulies, whose television career includes memorable performances on ER, The Good Wife, and The Morning Show, will also serve as an executive producer. Goodwin, who created the historical drama Victoria, is adapting her own novel and serving as showrunner. She describes the story as one that explores mothers and daughters, society's expectations, and what happens when money starts influencing just about every decision people make.

The production also includes executive producer Stacey Snider, with Fifth Season and MGM+ Studios co-producing. Catherine Morshead, Sandra Goldbacher, and Edward Hall are attached to direct. And with Goodwin behind the series, there's good reason to expect a little more than beautiful costumes and fancy dinner parties. Her previous work on Victoria showed how much storytelling potential there is when personal ambitions collide with the expectations of high society.

When Will ‘The American Heiress’ Premiere?

Production on The American Heiress is scheduled to begin in the United Kingdom in November 2026, although MGM+ has not announced an official premiere date. The series will air on MGM+ in the United States and several international markets, including the United Kingdom, Germany, Italy, Spain, the Netherlands, and Latin America. The actress playing Cora Cash has not yet been announced, so there's still a major casting reveal to come.

For now, we'll be keeping an eye on this one. Wealthy American families trying to conquer British high society, complicated romances, and mothers determined to control their daughters' futures? Sounds like the kind of mess that could make for some very entertaining television.
