5 Surprising New Roles: What Jack Gleeson (King Joffrey) Is Doing Now In 2025
The question of "What happened to Jack Gleeson?"—the actor who delivered one of television’s most memorably malicious performances as King Joffrey Baratheon in HBO's *Game of Thrones*—has finally been answered with a definitive, and surprising, career comeback. After famously stepping away from the screen to pursue academia, Gleeson has returned to acting with a series of high-profile projects, culminating in a major 2025 role that promises to cement his status as a versatile performer. As of December 21, 2025, Gleeson is a central figure in a new Netflix series, proving his hiatus was merely a strategic intermission, not a retirement.

However, he has since clarified that those rumors were exaggerated, and his break was primarily to focus on his education. His return is now in full swing, with significant roles in streaming and prestige television that are allowing him to shed the shadow of the Boy King and showcase a new, mature range.

The Post-Westeros Comeback: From Philosophy to Netflix's 'House of Guinness'
Gleeson’s decision to step away from the spotlight after the "Purple Wedding" episode of *Game of Thrones* was a deliberate choice to prioritize his personal and academic life. He enrolled at Trinity College Dublin, where he completed a degree in philosophy and theology, a pursuit he had considered turning into a Ph.D. and a lecturing career. This period of academic focus provided a necessary grounding after the intense scrutiny that came with playing one of television's most hated villains.
His return to the screen was gradual, beginning with the 2020 British sitcom *Out of Her Mind*, where he played the character Casper. However, his true comeback has been marked by a transition into significant, high-profile projects that are redefining his public image.
The 'House of Guinness' Main Role (2025)
The biggest news regarding Jack Gleeson's career in 2025 is his main role in the highly anticipated Netflix series, *House of Guinness*. The series, which chronicles the history and legacy of the famous Irish brewing family, is a major vehicle for the actor.
In *House of Guinness*, Gleeson portrays the character Byron Hughes (sometimes cited as Byron Hedges), a newfound cousin within the Guinness family. Byron is a crucial member of the main cast, a character sent to New York to develop relationships with American contacts for the family business. This role is arguably his most significant since *Game of Thrones*, placing him back in a potentially long-running series and offering a stark contrast to the sheer malice of Joffrey Baratheon. The project, which blends ambition, wit, and Irish history, is scheduled to be a major event on the streaming platform, with some reports mentioning a September 2025 release.
Shedding the Joffrey Shadow: Versatile New Roles (2023-2025)
Gleeson’s return has been characterized by an eclectic mix of roles in drama, fantasy, and adventure, demonstrating a clear desire to avoid typecasting. His recent work highlights his versatility and commitment to independent and quality projects.
1. Thomas Wentworth in 'The Famous Five' (BBC)
In the BBC's adaptation of Enid Blyton’s classic adventure books, *The Famous Five*, Gleeson took on the role of Thomas Wentworth. Wentworth is a villainous character who appears in the episodes based on the book *Five Go To Smuggler's Top*. The role, which sees him sporting a mustache and trading a crown for a period costume, allowed him to play a different kind of antagonist—a more subtle, classic villain—and proved he was comfortable returning to mainstream television.
2. Robin Goodfellow in 'The Sandman' (Netflix)
Gleeson also entered the world of Neil Gaiman's fantasy with a recurring role in Netflix’s *The Sandman*. He was cast as Robin Goodfellow, a character that draws on classic folklore and further showcases his ability to transition between genres. While a smaller role, his appearance was a welcome sight for fans and demonstrated that he was steadily building a new portfolio of work.
3. In the Land of Saints and Sinners (Film)
The actor appeared in the 2023 Irish thriller film *In the Land of Saints and Sinners*, starring alongside Liam Neeson and Kerry Condon. This project marked a significant step into serious cinema, allowing him to flex his dramatic muscles in a story rooted in his home country. The film, set in a remote Irish village, provided a gritty, grounded role far removed from the high fantasy of Westeros.
4. Safe Harbor (TV Series)
Looking ahead, Gleeson has also been cast in the upcoming television series *Safe Harbor*, which is being developed by Mark Williams, the creator of the hit show *Ozark*. The project promises another complex and potentially long-running narrative, signaling that his acting career is on a firm and upward trajectory, with producers eager to cast him in sophisticated, character-driven dramas.
Jack Gleeson has successfully navigated the challenge of being typecast after playing an iconic role like King Joffrey Baratheon. By prioritizing his personal growth through philosophy and theology studies, and then carefully selecting roles that highlight his range—from the historical drama of *House of Guinness* to the adventure of *The Famous Five*—he has managed to craft a compelling and unique second act to his career. His 2025 projects are a testament to his talent and commitment, ensuring that fans will be seeing much more of the talented Irish actor for years to come.
