Keoghan on PEAKY BLINDERS role

Barry Keoghan has long been obsessed with joining the PEAKY BLINDERS universe, but timing was never on his side—until now. The 33-year-old Dublin actor spent years pestering casting directors with hopeful texts asking if there was any chance of landing a role in Steven Knight’s phenomenon series, only to be repeatedly told it was an availability issue. That all changed when he was offered the opportunity to play Cillian Murphy’s son in PEAKY BLINDERS: THE IMMORTAL MAN, the highly anticipated feature continuation that just hit UK and Irish cinemas. It was, as Keoghan puts it, a no-brainer.
Sitting down with David McCullagh on RTE Radio One, Keoghan reflected on how much the iconic show means to him and how surreal it felt to finally step into its world. He spoke candidly about the nerves that come with joining such a beloved series with a fiercely dedicated fanbase—there’s always pressure to live up to expectations when stepping into an established universe. But those concerns dissolved when he realized he’d be working directly with Steven Knight himself and Cillian Murphy, the show’s magnetic centerpiece. Having those creative heavyweights in his corner was reassurance enough that he’d be in good hands.
It’s worth noting that Keoghan and Murphy had already formed a genuine friendship on the set of Christopher Nolan’s DUNKIRK, where they worked together years earlier. Their on-screen chemistry and off-screen rapport made the reunion feel less like a professional obligation and more like a natural collaboration between two actors who genuinely respect each other’s craft. That existing relationship likely made the transition into PEAKY BLINDERS: THE IMMORTAL MAN feel more comfortable, even as the weight of joining such a legendary project settled in.
The path to landing this role had an unexpectedly human touch. Keoghan revealed that a cheeky Father’s Day text to Knight ultimately helped seal the deal—a small, personal gesture that somehow bridged the gap between years of unanswered casting inquiries and finally getting his shot at the role he’d been chasing. It’s the kind of story that reminds us that sometimes persistence mixed with a bit of humor and genuine passion can crack open doors that seemed firmly shut.
The early reviews have been overwhelmingly positive, with audiences particularly praising Keoghan’s performance in the film. His portrayal of Murphy’s son has resonated with both longtime PEAKY BLINDERS devotees and newcomers alike, proving that his years of wanting to be part of this world weren’t misplaced enthusiasm. He brought something authentic and compelling to the character, making the film’s release feel like a genuine cultural moment rather than just another franchise extension.
Beyond PEAKY BLINDERS, Keoghan has been championing fellow Irish talent as the awards season reaches its crescendo. He’s been enthusiastically supporting his pal Jessie Buckley, who’s nominated for an Oscar for her extraordinary performance in Chloé Zhao’s HAMNET. Keoghan’s praise for Buckley is genuine and effusive—he watched the film at Paul Mescal’s invitation and found himself crying, deeply moved by the emotional depth and grace of her work. He’s hopeful that Irish luck will carry Buckley through on Oscars night, recognizing that she’s delivered something truly special that deserves recognition on cinema’s biggest stage.
There’s something touching about the way Keoghan speaks about his peers and his craft—he’s clearly someone who loves cinema in its truest form, who gets moved by great acting and great storytelling, and who understands that landing a role in something as culturally significant as PEAKY BLINDERS is a gift earned through perseverance. His journey to this moment, marked by years of hope, a lucky Father’s Day text, and finally, an opportunity to shine alongside one of Ireland’s finest actors, tells a story about never giving up on the work that matters to you. For fans of PEAKY BLINDERS, his presence in THE IMMORTAL MAN feels less like a casting choice and more like an inevitability—like he was always meant to be part of this world.
