There was always going to be pressure stepping into the shadow of Cillian Murphy’s Tommy Shelby. For six seasons of Peaky Blinders, Murphy defined modern television anti-heroism with icy restraint and strategic brilliance. But if early reports are to be believed, Barry Keoghan has no intention of mimicking the legacy. As Duke Shelby—Tommy’s long-lost, illegitimate son—Keoghan is not filling shoes. He is burning the floorboards.
Critics who have screened early footage describe his performance as volatile, coiled, and frighteningly direct. Where Tommy calculated, Duke reacts. Where Tommy negotiated, Duke punishes. And where later seasons showed the Shelby empire inching toward political legitimacy, Duke appears determined to drag it back into the mud from which it rose.
One insider described the shift bluntly: “It feels like 1919 all over again.”
That phrase, reportedly echoed by Ada Shelby within the story itself, carries enormous weight. The year 1919 marked the gang’s earliest days—when razor blades were sewn into caps and every dispute was settled with fists or bullets. It was a time before Parliament, before boardrooms, before the illusion of refinement. To say Duke is reviving that era is to suggest he is dismantling years of careful transformation engineered by his father.
Tommy Shelby’s arc was defined by ambition. He wanted legitimacy—titles, influence, proximity to power. He fought to move the Peaky Blinders from the betting shops of Birmingham to the corridors of Westminster. Even when violence remained part of his toolkit, it became a means to an end.
Duke, however, seems uninterested in ends.
Keoghan’s interpretation reportedly leans into the character’s fractured upbringing and outsider status. Unlike his half-siblings, Duke did not grow up inside the structured chaos of the Shelby household. He arrived late, carrying resentment and a need to prove himself. That chip on his shoulder becomes a governing philosophy. Leadership, under Duke, is not about strategy. It’s about dominance.
Industry observers note that Keoghan’s intensity feels almost feral. His Duke doesn’t speak in quiet monologues; he erupts. Scenes that might once have been handled with backroom bargaining now reportedly escalate with alarming speed. It’s a portrayal that strips away the polish of the later seasons and restores a kind of street-level brutality.
And that may be precisely the point.
Tommy’s exile—prolonged and self-imposed—created a vacuum. Duke steps into it not as a caretaker but as a conqueror. Ada’s unease signals that the family recognizes the danger. The empire Tommy built was fragile, balanced between crime and respectability. Duke’s zero-mercy approach threatens to undo that balance entirely.
Yet critics aren’t dismissing the shift. Many suggest it injects fresh electricity into a story that risked becoming too polished. By reintroducing unpredictability, Keoghan reminds audiences what made the early seasons so gripping: the sense that anything could explode at any moment.
There’s also a generational tension at play. Duke represents a post-war anger untempered by Tommy’s long view. He didn’t claw his way up from the trenches with a master plan; he inherited a throne and dares anyone to question his claim. That arrogance—combined with Keoghan’s magnetic unpredictability—creates a leader who feels both inevitable and unstable.
If Tommy Shelby was the architect of the modern Peaky Blinders, Duke may be its demolition crew.
And in that destruction lies the drama.
For viewers accustomed to Murphy’s steely calm, Keoghan’s ruthlessness may be shocking. But shock is exactly what the Shelby saga was built on. In returning to the raw violence of 1919, Duke doesn’t just honor the gang’s origins—he weaponizes them.
The question now isn’t whether he can lead.
It’s whether anything will survive his rule.
