The Gentlemen TV series cast: Roles & Character Guide

The Gentlemen TV series cast combines established British performers with international talent, creating a sharp ensemble for the show’s aristocratic crime comedy. Theo James leads the series as Eddie Horniman, while Kaya Scodelario plays Susie Glass, the criminal operator whose family business is tied to Eddie’s inherited estate.

The central conflict works because the cast represents two connected worlds. Eddie belongs to an old aristocratic family and inherits Halstead Manor, while Susie understands the criminal organization operating beneath the estate. Their relationship shifts between negotiation, cooperation, distrust, and mutual respect as the story progresses.

The leading performances define the show’s balance between inherited privilege and organized crime. Eddie begins as a disciplined outsider who wants to protect his family and remove the criminal enterprise from his property. Susie, by contrast, already understands the business, its risks, and the people who benefit from it.

Eddie Horniman — Theo James

Theo James plays Edward “Eddie” Horniman, the younger son who unexpectedly becomes the Duke of Halstead. Eddie is a former Army officer with a controlled manner and strong sense of responsibility. His initial plan is straightforward: resolve the estate’s criminal problem and restore control of his family’s future.

That plan becomes difficult once Eddie recognizes that the business beneath Halstead Manor is larger and more profitable than expected. His military discipline, social position, and ability to assess risk gradually make him effective in negotiations. The character’s major arc is the transition from reluctant landlord to active strategist.

Susie Glass — Kaya Scodelario

Kaya Scodelario plays Susie Glass, the daughter of Bobby Glass and the practical manager of the family’s cannabis empire. Susie is calm under pressure and comfortable dealing with threats, debts, rival operators, and complicated alliances.

She initially views Eddie as an obstacle connected to property the organization needs. Over time, their arrangement develops into a more balanced partnership. Susie provides criminal-world knowledge, while Eddie brings aristocratic access, strategic thinking, and a willingness to challenge established power structures.

Freddy Horniman — Daniel Ings

Daniel Ings plays Freddy Horniman, Eddie’s older brother. Freddy expects his family position to protect him, but his impulsive choices and financial problems repeatedly create danger for the Horniman household.

Freddy is not simply a rival to Eddie. He is also a source of family pressure and dark comedy. His behavior forces Eddie to confront problems that cannot be solved through inheritance or polite negotiation.

Lady Sabrina Horniman — Joely Richardson

Joely Richardson plays Lady Sabrina Horniman, the family matriarch and mother of Eddie and Freddy. She represents the older generation’s connection to Halstead Manor and understands more about the estate’s unusual arrangements than Eddie first realizes.

Her composed presence contrasts with Freddy’s instability and Eddie’s changing relationship with power. She also reinforces the show’s interest in inherited wealth, family reputation, and the secrets hidden behind an elegant country estate.

Geoff Seacombe — Vinnie Jones

Vinnie Jones plays Geoff Seacombe, the trusted groundskeeper and longtime associate of the Horniman family. Geoff is practical, loyal, and closely connected to the estate.

His knowledge of Halstead Manor gives Eddie an important source of support. Geoff also helps bridge the gap between the family’s formal aristocratic identity and the harder realities surrounding the property.

The supporting cast gives the series its wider criminal structure. Bobby Glass’s organization is not presented as a single-person operation. It depends on management, growers, intermediaries, family loyalty, and relationships with people who want access to its wealth.

Bobby Glass — Ray Winstone

Ray Winstone plays Bobby Glass, the founder and patriarch of the Glass criminal empire. Although he is imprisoned, Bobby remains the organization’s ultimate authority. His influence reaches through Susie and the network built around the cannabis business.

Bobby is important because he sees the criminal enterprise as both a business and a test of character. His interest is not limited to short-term profit. He also evaluates who has the judgment, intelligence, and ruthlessness required to control the organization.

Stanley Johnston — Giancarlo Esposito

Giancarlo Esposito plays Stanley Johnston, an American billionaire whose wealth and confidence make him a serious outside contender. Stanley approaches the criminal business through investment, leverage, and strategic acquisition.

His presence expands the conflict beyond local gang rivalries. Stanley represents a polished form of power that can be just as threatening as direct violence. He also tests whether Eddie and Susie can defend their partnership against someone with greater financial resources.

Henry Collins — Max Beesley

Max Beesley plays Henry Collins, a boxing promoter and criminal operator who becomes involved with Susie and the wider Glass organization. His public polish hides a competitive and ambitious nature.

Henry’s role emphasizes the show’s recurring idea that respectable businesses and criminal enterprises can overlap. His interests eventually place him in direct conflict with Susie and create another challenge for Eddie’s developing authority.

Jimmy Chang — Michael Vu

Michael Vu plays Jimmy Chang, a cannabis grower working inside the underground operation. Jimmy’s role connects the criminal organization to the day-to-day production that supports its larger network.

He also contributes to the show’s mixture of tension and humor. The operation may be carefully structured, but individual decisions can quickly create supply problems, misunderstandings, and unwanted attention.

The easiest way to track the ensemble is to separate the story into three layers: Eddie’s family, Susie’s organization, and the rivals who attempt to exploit the conflict between them. This structure prevents secondary characters from blending together during the fast-moving negotiations.
