The upcoming Peaky Blinders cinematic finale, The Immortal Man, is already generating enormous anticipation among fans, and one casting announcement in particular has intensified the excitement. Irish actor Barry Keoghan, known for his unsettling screen presence and fearless performances, has reportedly brought a striking new energy to the production. According to actress Sophie Rundle, early whispers from the set suggest that Keoghan’s arrival immediately shifted the atmosphere of the project.
Rundle, who portrays Ada Shelby in the acclaimed series Peaky Blinders, has followed the film’s production closely. When news broke that Keoghan had joined the cast of The Immortal Man, she admitted she was thrilled by the possibility of what his unique acting style could bring to the story’s final chapter.
Keoghan had recently captured global attention with his eerie and viral performance in Saltburn, where his unsettling charisma became one of the film’s most talked-about elements. That same unpredictable quality appears to be exactly what the filmmakers were looking for when adding new faces to the world of Birmingham’s most dangerous gang.
According to behind-the-scenes accounts Rundle referenced, the crew reportedly felt the shift the moment Keoghan stepped into his first wardrobe fitting. Rather than adopting the sharply polished posture associated with the Shelby family’s tailored suits, Keoghan apparently approached the character from a completely different angle.
Crew members described him slouching slightly, shoulders loose but tense with coiled energy. Instead of admiring himself in the mirror like a typical costume fitting might involve, he reportedly stared straight ahead with an unblinking intensity, as if already locked inside the mind of his character. The moment left an impression on those present, suggesting that Keoghan was building something far more unpredictable than the refined menace often seen in the series.
Rundle suggested that this raw approach adds a new dimension to the film’s tone. The Shelby brothers have always been defined by their composed brutality and calculated ambition, but Keoghan appears to represent a more chaotic force entering their world. His performance style leans toward unpredictability, a quality that could disrupt the balance of power within the story.
Fans of the series may also notice a thematic parallel. Rundle pointed out that Keoghan’s feral energy mirrors the dangerous unpredictability that Cillian Murphy brought to the role of Tommy Shelby during the earliest days of the show. In the first season, Murphy’s character carried a volatile intensity that made every scene feel as though violence or brilliance could erupt at any moment.
Keoghan’s arrival could reintroduce that same sense of instability, creating a new wildcard within the narrative just as the saga reaches its cinematic conclusion.
While details about the film’s plot remain tightly guarded, the presence of such a distinctive actor suggests that the finale will not simply revisit familiar dynamics. Instead, it may introduce fresh tensions capable of shaking the Shelby empire one last time.
For audiences who have followed the story for more than a decade, the idea of Keoghan bringing his chaotic Irish grit into the Peaky Blinders universe only heightens the anticipation. If the early whispers from the set are any indication, The Immortal Man could deliver a finale filled with the same unpredictable danger that made the series unforgettable in the first place.
