From Summerhill to Shelby: Barry Keoghan Cements A-List Status with ‘Peaky Blinders’ and Upcoming ‘Mad Hatter’ Role
DUBLIN, Ireland — In the span of a single decade, Barry Keoghan has transformed from a persistent young actor answering casting calls in shop windows to one of the most formidable forces in global cinema. As of March 2026, the Dublin-born star is dominating headlines once again, following the high-stakes release of the Peaky Blinders feature film and the official confirmation of his next transformative role in the “Alice in Wonderland” universe.
The ‘Immortal’ Arrival: Duke Shelby Takes the Reins
On March 20, 2026, the long-awaited film Peaky Blinders: The Immortal Man made its global debut on Netflix after a limited theatrical run that began on March 6. Keoghan stars as Erasmus “Duke” Shelby, the illegitimate son of the legendary Tommy Shelby (played by Cillian Murphy). Set against the grim backdrop of 1940s Birmingham during World War II, the film serves as a pivotal passing of the torch.
Critics have lauded Keoghan’s performance as Duke, describing his portrayal of the Birmingham underworld’s new leader as “hauntingly intense” and “calculating.” The film explores the friction between the original Shelby generation and the “wild card” Duke, who has spent the years of Tommy’s exile consolidating power. Series creator Steven Knight has hinted that Keoghan’s performance in The Immortal Man may serve as a foundation for a future spin-off series focusing on the next generation of the Shelby empire.
Stepping into the Looking Glass: The ‘Mad’ Announcement
While fans were still processing his arrival in Birmingham, Keoghan made another major waves during a March 14, 2026, interview on Heart Radio. The 33-year-old actor officially confirmed he will take on the iconic role of the Mad Hatter in a new standalone film titled Mad. The project, reportedly written and directed by Lorene Scafaria, is an origin story focusing on the eccentric character from Lewis Carroll’s Alice’s Adventures in Wonderland.
The news follows years of speculation and a viral appearance at the 2024 Met Gala, where Keoghan’s Victorian-inspired attire was widely interpreted as a “soft launch” for the role. Production insiders suggest the film will be a psychological dive into the character’s descent into madness, perfectly aligning with Keoghan’s reputation for portraying complex, unsettling individuals.
The Human Cost of Fame: Facing the ‘Nasty Side’ of Social Media
Despite his professional triumphs, Keoghan has recently been candid about the personal toll of his rising profile. On March 20, 2026, during an appearance on SiriusXM’s The Morning Mash Up, the actor addressed the “nasty side” of social media, specifically citing online bullying regarding his physical appearance. Keoghan admitted that the abuse has at times made him want to “hide away” and even reconsider his career on screen.
“When that starts leaking into your art, it becomes a problem,” Keoghan shared, expressing particular concern for his three-year-old son, Brando, who he worries will one day read the vitriol directed at his father. The actor’s vulnerability has sparked a wider conversation within the industry about the protection of performers in the digital age.
A Journey of Resilience: From Foster Care to the Oscars
Keoghan’s current success is underscored by a background of significant hardship. Born on October 18, 1992, in the Summerhill district of Dublin, he faced a tumultuous childhood. After losing his mother to a heroin overdose when he was just 12 years old, Keoghan and his brother Eric spent seven years in the foster care system, moving through 13 different homes before being raised by their grandmother and aunt.
His entry into acting was equally unconventional. In 2011, he saw a casting notice for the film Between the Canals in a shop window and persistently called the producers until he was given a part. His international breakthrough arrived in 2017 with dual roles in Christopher Nolan’s Dunkirk and Yorgos Lanthimos’s The Killing of a Sacred Deer. Since then, he has built an enviable filmography, including a BAFTA win and an Academy Award nomination for 2022’s The Banshees of Inisherin, and a Golden Globe nomination for his leading role in the 2023 psychological thriller Saltburn.
What’s Next: The Beatles and Beyond
Keoghan’s schedule shows no signs of slowing down. In addition to his recent release of the crime thriller Crime 101 (February 2026) alongside Chris Hemsworth and Mark Ruffalo, he is preparing for a monumental 2027. He has been cast as Sir Richard Starkey, better known as Ringo Starr, in Sam Mendes’ ambitious four-part Beatles biopic series. Keoghan is reportedly already taking drum lessons to prepare for the role, which will tell the story of the Fab Four from the perspective of each individual member.
As he navigates the heights of Hollywood, Keoghan remains a symbol of resilience for many in his native Ireland and beyond. Whether he is leading the Peaky Blinders or navigating Wonderland, his career continues to be defined by a refusal to be typecast and a commitment to raw, authentic storytelling.
