Rebecca Ferguson makes her explosive debut in Peaky Blinders: The Immortal Man on Netflix today, March 20, 2026. The Dune star plays Kaulo, a mystical and mysterious twin who pulls Cillian Murphy‘s isolated Tommy Shelby back into the gritty world of Birmingham for an epic final chapter.

Ferguson Plays Dual Role as the Mystical Kaulo

Rebecca Ferguson doesn’t just debut, she captivates audiences as Kaulo, one half of mystical identical twins. Her sister Zelda passed away years ago, but Kaulo claims to channel her spirit from beyond. According to Ferguson herself, her character arrives ‘airily’ and ‘earthily’ with a razor-sharp eye on the future of Duke, Tommy’s estranged son.

The Swedish actress describes her mission as simple yet profound. ‘My character comes in to persuade Tommy to break out of isolation and take control, guiding his son,’ Ferguson explains. She injects a supernatural element into the 1940 Birmingham setting, as Kaulo becomes Tommy’s unexpected bridge back to the living.

An Epic 1940 Birmingham Showdown Unfolds

Set against the chaotic backdrop of World War II, the film explores Tommy Shelby‘s painful isolation in a rural house. Cillian Murphy returns as the legendary gypsy gangster after years of self-imposed exile. His son, Duke (played by Barry Keoghan), now runs the Peaky Blinders with an iron fist, entangled in dangerous dealings with Nazi sympathizer John Beckett (played by Tim Roth).

Ferguson’s Kaulo acts as the catalyst for Tommy’s return to power. The film builds toward an unforgettable climax where counterfeiting schemes, wartime betrayals, and family loyalty collide. Stephen Graham returns as Hayden Stagg, while Sophie Rundle reprises her role as Ada Thorne, fighting for justice at a devastating personal cost.

Star-Studded Cast Elevates the Final Shelby Chapter

Actor	Character & Background
Rebecca Ferguson	Kaulo, mystical twin with supernatural powers
Cillian Murphy	Tommy Shelby, self-exiled gang leader haunted by loss
Barry Keoghan	Duke Shelby, Tommy’s son ruling with ruthless power
Tim Roth	John Beckett, Nazi operative threatening Britain

Cillian Murphy personally recruited Barry Keoghan by text message on Father’s Day, a casting moment as memorable as the onscreen chemistry between father and son. The ensemble reflects creator Steven Knight‘s ambition to deliver a conclusive, emotionally devastating final chapter to Tommy’s saga.

Why This Debut Matters Beyond Peaky Blinders

Rebecca Ferguson joins the franchise at its most consequential moment. She’s worked across the Dune franchise alongside Timothée Chalamet, but this role marks her entry into one of television’s most iconic universes. Her character doesn’t just serve as a supporting player, she’s the emotional anchor pulling the protagonist back from the brink.

The 91% Rotten Tomatoes rating proves audiences are captivated. Critics praise the film for ‘capping off Tommy Shelby’s story with grit and swagger, as a satisfying conclusion that also stands tall on its own self-contained terms.’ Ferguson’s mystical presence adds layers of psychological depth previously unexplored in the franchise.

Will Rebecca Ferguson’s Mystical Character Return in Future Peaky Blinders Stories?

With Steven Knight teasing a new generation Peaky Blinders spinoff series already in development, questions swirl about whether Kaulo‘s supernatural influence extends beyond The Immortal Man. Her character embodies the mystical gypsy traditions that have always haunted the franchise’s core mythology.

The film’s ending proves definitively that Tommy Shelby‘s chapter closes after decades of storytelling, yet Kaulo’s presence suggests the supernatural elements of the Peaky universe remain unresolved. Knight has confirmed a sequel series exploring Duke and the next generation, leaving potential for Ferguson’s character to influence future storylines from beyond the grave.
