Star-Studded 'Belgravia' Cast Revealed: Alice Eve, Tamsin Greig, Harriet Walter & Philip Glenister Lead Julian Fellowes' ITV-Epix Period Drama

Exclusive: The Power Players Behind 'Belgravia'

The period drama landscape just got a major injection of star power. In an exclusive report detailed in Screenshot (550).png, ITV and Epix have announced the lead cast for Belgravia, the highly anticipated new series from Downton Abbey creator Julian Fellowes. The ensemble is a veritable who's who of British acting royalty: Alice Eve, Tamsin Greig, Harriet Walter, and Philip Glenister will headline this lush, scandal-filled saga set in 1840s London.

Produced by Carnival Films – the same powerhouse behind Downton Abbey and The Crown – Belgravia promises to be a sumptuous exploration of class, ambition, and buried secrets. Fellowes adapts his own 2016 novel, originally serialized in a Dickensian digital format that included an audiobook narrated by Juliet Stevenson. The series is directed by John Alexander (Trust Me, Jamestown) and executive produced by Carnival's Gareth Neame, Nigel Marchant, and Liz Trubridge.

Meet the Cast: From Sci-Fi to High Society

Alice Eve as Susan Trenchard

Alice Eve, best known for her turn as Dr. Carol Marcus in J.J. Abrams' Star Trek Into Darkness and her chilling performance in the Black Mirror episode Nosedive, steps into the role of Susan Trenchard. Described as the beautiful daughter of a successful merchant, Susan is a character ripe with dramatic potential. Eve's career has straddled blockbuster spectacle and intimate character work, making her an inspired choice to navigate the treacherous waters of 19th-century social climbing.

Tamsin Greig as Anne Trenchard

Tamsin Greig, beloved for her comedic genius in Episodes and Green Wing, takes on the role of Anne Trenchard. The matriarch of the Trenchard family, Anne is a woman caught between her husband's newfound wealth and the rigid expectations of the aristocracy. Greig's ability to blend warmth with steel will undoubtedly bring depth to this complex character. After finishing the critically acclaimed Showtime series Episodes, this role marks a return to period drama for the actress.

Philip Glenister as James Trenchard

Philip Glenister, the gravel-voiced star of Outcast and the classic Life on Mars, plays James Trenchard, the ambitious businessman at the heart of the story. Glenister, who recently appeared in Sky's comedy Living The Dream, brings a rugged authenticity to the role. James is a merchant who has made his fortune through trade, and now finds himself rubbing shoulders with the old-money elite in the newly developed Belgravia district. His journey from wealth to acceptance is the engine that drives the drama.

Harriet Walter as the Countess of Brockenhurst

Harriet Walter, a true dame of the British stage and screen, portrays the Countess of Brockenhurst. Walter is no stranger to period drama royalty: she played the Dowager Lady Shackleton in Downton Abbey and recently portrayed Princess Alice in The Crown. The Countess is the embodiment of the old guard: aristocratic, shrewd, and determined to maintain her family's status in the face of the rising industrial nouveau riche. Walter's commanding presence promises scenes of delicious tension.

The Story: Secrets, Scandal, and the Birth of a New London

Belgravia begins on the eve of the Battle of Waterloo in 1815, at the Duchess of Richmond's legendary ball in Brussels. Among the glittering guests are James and Anne Trenchard, enjoying the fruits of their trading success. Their young daughter Sophia catches the eye of Edmund Bellasis, the son and heir of one of England's most powerful families. Twenty-five years later, when both families are settled in the exclusive new neighborhood of Belgravia, the secrets of that fateful night – and the choices made then – come crashing back with devastating consequences.

The series is a gripping tale of love, betrayal, and the price of ambition. Fellowes, who built his reputation on dissecting the British class system in Downton Abbey, here turns his attention to the tension between the established aristocracy and the self-made industrialists who were reshaping Victorian England. The book was originally released in weekly digital installments, a modern twist on the serialized novels of Charles Dickens – fitting for a story that explores how the past echoes into the present.

Behind the Scenes: The Creative Team

Julian Fellowes is adapting his own novel, ensuring the translation from page to screen retains his signature wit and historical nuance. Direction is handled by John Alexander, whose work on Trust Me and Jamestown demonstrates a keen eye for both psychological tension and period detail. The production is in the hands of Colin Wratten, a producer known for his work on Killing Eve.

The executive producing team is stacked: Carnival Films' Executive Chairman Gareth Neame, who has been instrumental in the global success of Downton Abbey, is joined by Nigel Marchant and Liz Trubridge. This pedigree suggests Belgravia will be a visual and narrative feast, with the production values that have become synonymous with Carnival's period dramas.

What This Means for ITV and Epix

For ITV, Belgravia is a major prestige play. The network has long been the home of British historical dramas, and this series aims to fill the void left by Downton Abbey. For Epix, the series continues its strategy of co-producing high-end UK period pieces, following Belgravia into a landscape where streamers and cable nets are hungry for content that appeals to an upscale, international audience.

The casting alone is a masterstroke. Each actor brings a devoted fanbase and proven critical acclaim. Alice Eve's sci-fi pedigree may attract younger viewers, while Harriet Walter's association with The Crown and Downton Abbey ensures the support of the core period drama audience. Tamsin Greig and Philip Glenister add the kind of everyman gravitas that makes these historical stories feel immediate.

As the entertainment world waits for a premiere date, one thing is clear: Belgravia is shaping up to be the can't-miss drama of the season. The secrets of the Trenchard and Bellasis families are about to spill onto screens, and if the source material is any indication, viewers are in for a wild, emotional ride through the glittering and corrupt world of Victorian high society.
