The release of Netflix’s ambitious new series has people talking, and much of the buzz centers around the House of Guinness cast. Premiering on September 25, 2025, the series dramatizes the rise and turmoil of the Guinness family, heirs to one of the most iconic brewing empires in history. With a mix of established stars and rising talents, the cast brings intensity, emotion, and realism to the 19th-century world of Dublin’s most famous dynasty.
For U.S. viewers, the intrigue is twofold: the Guinness name already holds weight thanks to the brand’s lasting popularity, and the show offers a gripping mix of family drama, power struggles, and historical storytelling. This article takes a closer look at the cast, their characters, and how their performances shape the show into one of Netflix’s standout releases of 2025.
Why the House of Guinness Cast Matters
In a series that explores inheritance battles, political upheaval, and family secrets, casting becomes everything. The Guinness name comes with real historical weight, and the actors needed to capture not only the humanity of these figures but also their symbolic importance.
The House of Guinness cast succeeds by grounding the drama in authentic performances. Instead of simple caricatures of wealth or power, they deliver layered portrayals: heirs unsure of their place, siblings torn between duty and resentment, and outsiders who disrupt the family’s empire.
The Core Family Members
Anthony Boyle as Arthur Guinness
At the center of the family is Arthur, the eldest son. Anthony Boyle, known for his intensity in previous period dramas, brings Arthur’s inner conflict to life. Raised with privilege and education, Arthur struggles between personal ambition and the crushing weight of being the heir.
Boyle gives Arthur nuance, balancing moments of pride with glimpses of doubt. His presence anchors the story, as every decision he makes ripples across the family and the brewery. For U.S. audiences, his portrayal resonates with the universal theme of reluctant leadership.
Louis Partridge as Edward Guinness
Edward, the youngest son, contrasts sharply with Arthur. Played by Louis Partridge, Edward is ambitious, energetic, and eager to shape the brewery’s future. His drive to expand the family business into international markets brings momentum to the show.
Partridge plays Edward with charisma and impatience, embodying the frustrations of a younger sibling determined to prove himself. This dynamic with Arthur provides much of the sibling rivalry that keeps viewers hooked.
Emily Fairn as Anne Guinness
Emily Fairn portrays Anne, the only daughter in the Guinness family. While she cannot directly inherit, she wields power through intellect, marriage alliances, and influence. Her portrayal offers a rare look into how women navigated male-dominated systems in the 19th century.
Anne’s role is pivotal in showing that family legacy wasn’t only defined by the sons. Fairn’s subtle performance highlights Anne’s emotional intelligence, giving the cast a crucial balance between ambition and compassion.
Fionn O’Shea as Benjamin “Ben” Guinness
Ben, the troubled sibling, is played with raw honesty by Fionn O’Shea. Unlike his brothers, Ben struggles with addiction and self-destruction. O’Shea captures both the vulnerability and chaos of a man overlooked in the succession conversation.
His unpredictable behavior injects tension into nearly every family scene, making Ben both tragic and compelling. In the broader context of the House of Guinness cast, Ben represents how dynasties often fracture under internal weaknesses.
The Outsiders Who Shape the Story
James Norton as Sean Rafferty
James Norton plays Sean Rafferty, a fictionalized foreman and fixer within the brewery. While not a Guinness by blood, his influence is undeniable. Norton’s performance balances loyalty with menace, showing how working-class figures could both support and threaten the elite.
Rafferty’s presence highlights that the Guinness empire was not built by family alone—it relied on individuals who often blurred the lines between ally and adversary.
Niamh McCormack as Ellen Cochrane
Ellen Cochrane, played by Niamh McCormack, is a passionate Irish nationalist who enters the Guinness orbit through romance and political tension. McCormack delivers fire and conviction, contrasting with the family’s wealth and privilege.
Her role ensures that the series doesn’t just focus inward on the family but also outward on Ireland’s broader struggle for identity and independence.
Seamus O’Hara as Patrick Cochrane
Patrick Cochrane, Ellen’s brother, is more militant in his politics. Played by Seamus O’Hara, Patrick brings sharp energy and conflict, pushing the Guinness family to confront their position in a divided Ireland.
Supporting Roles Adding Depth
Beyond the leads, the House of Guinness cast features a strong supporting lineup:
- Dervla Kirwan as Aunt Agnes Guinness, embodying tradition and reminding the heirs of their family’s responsibilities.
- Michael McElhatton as John Potter, the family’s butler, who often knows more than he lets on.
- Jack Gleeson as Byron Hedges, an illegitimate cousin whose American ties complicate business dealings.
- Danielle Galligan as Lady Olivia Hedges, navigating society’s expectations while tied to the Guinness name.
- Hilda Fay as Sultan, representing Dublin’s working-class perspective in a story often dominated by aristocracy.
These roles enrich the world-building, showing how the Guinness story touched not just the family but also society at large.
How the Cast Balances History and Drama
The Guinness family is real, but House of Guinness is not a documentary. The cast had to strike a delicate balance: honoring historical legacies while also delivering a story that entertains modern audiences.
- Arthur and Edward’s rivalry reflects documented tensions about succession and the future of the brewery.
- Anne’s character expands on the limited historical record to highlight women’s often-overlooked influence.
- Ben’s portrayal, though dramatized, embodies the pressures faced by younger heirs overshadowed by siblings.
- Rafferty, while fictional, represents the invisible workforce and enforcers who sustained dynasties.
This blend of fact and dramatization gives the cast freedom to explore emotional truths, even if not every storyline is pulled directly from history.
Reception of the House of Guinness Cast
Since the premiere, critics have praised the casting choices as one of the series’ greatest strengths. Highlights include:
- Anthony Boyle’s Arthur: commanding yet vulnerable, giving the audience someone to root for and question simultaneously.
- Louis Partridge’s Edward: a breakout performance that balances charm with ruthless ambition.
- Emily Fairn’s Anne: quiet but powerful, often grounding the family’s chaos.
- Fionn O’Shea’s Ben: heartbreaking in his spiral, offering some of the show’s most emotional moments.
- James Norton’s Rafferty: a scene-stealer who adds danger and unpredictability.
The ensemble has been compared to casts of major period dramas like The Crown and Succession, thanks to their chemistry and ability to make family conflict both intimate and epic.
Why U.S. Audiences Are Drawn to the Cast
Although the show is rooted in Irish history, it resonates strongly with U.S. viewers. The reasons are clear:
- Global Recognition of Guinness: The brand is already a household name in the United States.
- Familiar Faces: Norton, Boyle, and Partridge are known from popular international projects.

What to Watch for in Future Seasons

- Will Arthur fully embrace leadership, or continue wavering?
- Can Edward’s ambition secure the brewery’s dominance or tear the family apart?

The answers depend on both writing and performance, keeping audiences invested in both the story and the actors bringing it to life.
