PBS is betting big on literary prestige with The Forsytes, a 2026 Masterpiece prequel to the Nobel Prize-winning Forsyte Saga. By framing the origin story of the wealthy Forsyte family before John Galsworthy’s novels, the series taps into the golden age of period drama—and assembles a transatlantic cast of familiar faces from Downton Abbey to Doctor Who. This isn’t just another costume show; it’s a strategic reclaiming of classic storytelling for a streaming era.
The final Downton Abbey film has come and gone. Miss Scarlet and All Creatures Great and Small continue to charm, but there’s a palpable hunger for something that feels both grandly literary and emotionally raw. Enter The Forsytes, Masterpiece PBS’s bold new 2026 series that isn’t an adaptation of a famous book—it’s a prelude to one. Based on the Nobel Prize-winning Forsyte Saga by John Galsworthy, the show explores the formative years of the Forsyte dynasty before the events of the novels, promising a fresh entry point into a cornerstone of early 20th-century literature.
Premiering Sunday, March 22 at 9 p.m. ET on PBS, The Forsytes arrives at a moment when the appetite for sophisticated period drama has never been higher. But this isn’t just about filling a scheduling gap. It’s a calculated creative gambit: taking a revered, dense novel cycle and extracting its origin story—the tensions, passions, and betrayals that forged a family—into something that feels immediate and bingeable. The series is created by Debbie Horsfield, the acclaimed writer behind the hit revival of Poldark, whose track record with Masterpiece PBS proves she knows how to blend sweeping romance with gritty class conflict.
What Makes ‘The Forsytes’ Different from Every Other Period Drama?
Traditional adaptations of The Forsyte Saga (most notably the BBC’s 1967 and 2002 versions) cover the novels’ main timeline. The Forsytes deliberately sets its narrative clock back, depicting the younger generation of Forsytes—James, Jolyon, and their sisters—as they navigate the treacherous waters of Victorian-era London society. The central conflict is timeless: the tension between familial duty and personal desire, between the cold calculus of wealth and the chaotic pursuit of love. The series tags its core themes as “desire, ambition, and betrayal,” but those are almost too neat. What Galsworthy, and now Horsfield, really explore is the psychology of accumulation—how a family built on stockbroking and social climbing defines itself through possessions, propriety, and the suppression of feeling.
This focus on the “before” story is a narrative masterstroke. It allows the series to stand on its own without requiring viewers to know the novels, while simultaneously creating a sense of dramatic irony for those familiar with the saga’s later tragedies. We watch these characters make choices that will echo for decades, building the very foundations of the conflict Galsworthy originally depicted. It’s an origin story for the aristocracy, and in 2026, that feels urgently relevant.
The Cast: A Masterclass in Typecasting and Discovery
Masterpiece PBS has assembled a ensemble that bridges British television royalty with rising international stars. The casting is not just accurate; it’s thematically resonant. Each actor carries a whiff of their most famous role into this new family drama, creating a fascinating layering effect for the audience.
At the top of the hierarchy are Stephen Moyer and Jack Davenport. Moyer, forever etched as the noble vampire Bill Compton from True Blood, plays Jolyon Forsyte Sr., the more emotionally open brother whose choices will define the family’s rift. Davenport, known to US audiences as the scheming media exec from The Morning Show and the charming Roger from Smash, takes on James Forsyte—the stern, tradition-bound elder brother. The dynamic between these two, already charged with off-screen baggage, will be the engine of the early episodes.
The pivotal role of Soames Forsyte—James’s son, who will become the central tragic figure of Galsworthy’s novels—goes to Australian actor Joshua Orpin. Orpin, who spent four seasons as the Kryptonian Connor Kent in Titans, has the physical presence and simmering intensity to portray Soames’s possessive, obsessive nature. This is a major step up, and the casting suggests Soames won’t be a mere villain but a product of his upbringing—trapped by the very fortune his father built.
Tuppence Middleton (Downton Abbey: A New Era, His Dark Materials) plays Frances Forsyte, James’s wife, whose own ambitions will be stymied by the era’s rigid expectations. Middleton has a knack for portraying poised women with fierce inner lives, and her scenes with Davenport will cut to the heart of a marriage built on social strategy rather than affection.
The wildcard is Millie Gibson as Irene Heron, the woman who becomes Soames’s wife and the source of his torment. Gibson is a breakout star from Doctor Who (as Ruby Sunday) and British soaps, and her casting is a signal of The Forsytes’ desire to attract a younger demographic. The Irene-Soames relationship is the emotional core of Galsworthy’s work, and Gibson’s ability to convey vulnerability and silent resistance will be make-or-break for the series.
Eleanor Tomlinson, beloved as Demelza Poldark, brings her warmth and strength to Louie Byrne, Jolyon’s love interest—a direct contrast to the Forsyte world. Tomlinson’s presence instantly connects The Forsytes to Masterpiece’s most successful recent period drama, creating a through-line for viewers.
The supporting cast is a who’s who of British television: Francesca Annis (Dune, The Libertine) as matriarch Ann Forsyte; Tom Durant-Pritchard (from Miss Scarlet) as Monty Dartie; and Josette Simon (Sanditon) as Ms. Ellen Parker Barrington. This depth of talent suggests PBS is playing to win, allocating a budget and cast roster that rivals any streaming prestige drama.
Why This Matters Right Now: The Prestige Game
Streamers have largely ceded the classic literary adaptation space. Netflix dabbles (think persuasian), but the sustained, novelistic adaptation of a dense, early 20th-century text is now PBS’s domain. The Forsytes is a statement: we still own this lane. With Horsfield at the helm—who demonstrated with Poldark that she can make class-conscious period drama feel urgent and sexy—the series has the potential to be the next Downton phenomenon.
Critically, by choosing a prequel, the showrunners sidestep the “we already know the story” problem that plagues adaptations of famous works. Viewers don’t need to have read Galsworthy (who won the Nobel in 1932) to be drawn into a story about a family’s scramble for status and happiness. The themes are evergreen, but the timing is specific: in an era of vast wealth inequality, the story of stockbrokers building empires through speculation and social maneuvering feels strikingly contemporary.
The casting of Moyer and Davenport also signals a desire for crossover appeal. These are actors known for modern, genre-adjacent work (True Blood, The Morning Show). Their involvement tells the industry—and the audience—that this isn’t a dusty heritage project. It’s a drama about desire and power, using the past as a lens.
The Viewing Strategy: Linear and Streaming, Masterpiece-Style
The Forsytes will air Sundays at 9 p.m. ET on local PBS stations, anchoring the traditional broadcast experience. For cord-cutters, it will be available via PBS Passport (the member benefit platform) and through a Masterpiece PBS subscription on Prime Video. This twin-pronged approach—linear for the loyal, streaming for the new—is Masterpiece’s standard playbook, and it’s proven effective for All Creatures and Miss Scarlet. Expect the first two episodes to drop on streaming immediately after the linear premiere, with subsequent episodes rolling weekly.
The Verdict: A Safe Bet That Could Soar
On paper, The Forsytes is a low-risk, high-reward proposition for PBS. It has:
- A Nobel Prize-winning source with public domain status (no licensing fees).
- A writer with a recent hit under her belt.
- A cast assembled from across the Masterpiece universe and beyond.
- Themes that resonate beyond the period setting.
The biggest question mark is tone: can it balance the inevitable grandeur of the production design with the intimate, often depressing, marital strife that defines Galsworthy? Early set photos suggest a lush, saturated palette—think Poldark meets The Crown. The teaser trailer, embedded above, hints at a score that is more sweeping than somber. This may be the key to its success: honoring the novel’s critique of the bourgeoisie while delivering the visual and emotional goods that keep audiences coming back.
For fans of Downton Abbey, The Forsytes offers the same mix of upstairs-downstairs dynamics, but with a darker, more philosophical undercurrent. For viewers of Poldark, it’s Horsfield’s return to the well of passion and class conflict. And for anyone looking for television that treats its source material with reverence while making it feel new, this is a must-watch.
