MGM+ has ordered The American Heiress, an eight-part period series with Julianna Margulies in a central role, adapting Daisy Goodwin’s 2011 novel for a multi-market streaming launch.
Margulies will play Isabella Cash, a mother who brings her daughter Cora to England in 1893. The trip is aimed at securing the one asset American money cannot command at home: a title. A hunting accident upends Cora’s plans when she wakes at Lulworth Castle, where the 12th Duke of Wareham and the shifting rules of the era test her certainties.
The package behind the order
Goodwin executive produces alongside FilmNation chief creative officer Stacey Snider. Margulies, Damian Keogh, Stella Merz and Kirstie Macdonald are also executive producers. Catherine Morshead, Sandra Goldbacher and Edward Hall will direct, and production is set to begin in the UK this month.
MGM+ will premiere the series in the U.S., UK, Germany, Italy, Spain, the Netherlands and Latin America, with Fifth Season handling global distribution.
Why this is a strategy, not just a show
The order leans on three de-risking moves that matter for anyone selling premium video.
- Pre-sold IP: Goodwin’s novel is already published, and her work on Victoria gives buyers a reference point for tone and audience.
- Established star: Margulies arrives with recognition from the streaming drama Paradise, which can help a new title cut through crowded catalogues.
- Seven-market launch: One commission spreads cost across multiple territories and supports a single global marketing idea.
Michael Wright, global head of MGM+, called the project “a seductive mix of captivating characters, old world class politics, and romantic ambition.” Goodwin framed it as a search for meaning “in a world distorted by money.”
Where it fits for advertisers
The period-romance lane can deliver a dependable, often female-skewing and upscale audience. For media planners, that is a useful contrast to broad action or sci-fi and can support categories from luxury retail to premium travel, especially on ad-supported streaming tiers.
The “romantic comedy of manners” framing also signals a lighter, rewatchable tone rather than prestige doom. Trailers and creative should lean into the core clash: American money versus English status.
For MGM+, the test is whether a star-led literary adaptation can drive subscriber acquisition across seven markets at once. If it works, expect more period IP with multi-territory pre-sales to follow.
