Movies Explore: Peaky Blinders: The Immortal Man Cast & Character Guide (New Faces Explained)

The Immortal Man cast, explained: every new face and returning ally

Peaky Blinders: The Immortal Man drops Tommy Shelby into a World War II Birmingham where old loyalties are fraying and new power players are circling. If you’re here because the trailer introduced characters you don’t recognize (or because Barry Keoghan’s role raised a hundred questions), this guide breaks down who’s who, what each character is doing in the story, and how the new faces connect to the Shelby legacy.

This post focuses on cast and character context, with plot kept broad and spoiler-light.

Quick watch info (cinemas vs Netflix)

The film has a limited theatrical run starting March 6, 2026, and begins streaming on Netflix on March 20, 2026.

The official trailer (and the key character clues inside it)

The fastest way to spot the film’s new status quo is to rewatch the trailer with names attached. Keep an eye out for Duke’s leadership era, Kaulo’s presence, and the “reasonable” kind of threat that makes Beckett dangerous.

Returning characters: where we find them now

Tommy Shelby (Cillian Murphy)

The movie picks up with Tommy in a self-imposed exile, mentally and emotionally wrecked by everything that came before. The key shift: this isn’t Tommy building an empire from hunger—this is Tommy trying (and failing) to outlive what he’s done.

Ada Thorne (Sophie Rundle)

Ada remains the clearest-eyed Shelby: she understands what power does to people, and she understands that wartime pressure doesn’t magically turn criminals into heroes. If Tommy is drifting, Ada is steering—especially when Duke starts running the Peakys like a throwback to their most brutal era.

Hayden Stagg (Stephen Graham), Charlie Strong (Ned Dennehy), Johnny Dogs (Packy Lee), Curly (Ian Peck)

These returning allies do something vital for a franchise movie: they keep it from feeling like “Tommy Shelby: Solo.” They also quietly answer a big fan fear: even in a new decade with a new war, Peaky Blinders still has its original bones—loyalty, logistics, and men who know where the bodies are buried.

New faces explained: the four characters who change everything

Erasmus “Duke” Shelby (Barry Keoghan)

Duke is the fulcrum of the movie. In the series, he arrives late as Tommy’s illegitimate son; in The Immortal Man, he becomes the heir who’s actually holding the knife. The tension isn’t only “will Duke replace Tommy?” It’s “what kind of Shelby is Duke becoming when Tommy isn’t there to restrain, guide, or terrify him?”

Beckett (Tim Roth)

Beckett isn’t the loud, theatrical villain type. He’s the convincing one—the man who can make betrayal sound like duty. He targets Duke with a scheme tied to undermining Britain by flooding the economy with counterfeit banknotes, pulling the Peakys into wartime stakes that are bigger than turf.

Kaulo (Rebecca Ferguson)

Kaulo is one of the film’s most intriguing additions because she represents the side of Peaky Blinders that has always hovered at the edges: Romani identity, spiritual threat, and the idea that Tommy’s “ghosts” aren’t just metaphors.

Without overexplaining: Kaulo’s connection to Duke’s family line makes her presence feel fated, and her impact on Tommy is personal in a way that politics and gang wars can’t match.

Elijah (Jay Lycurgo)

Elijah is positioned as Duke’s right-hand man, which matters because Duke is not operating in Tommy’s old structure. If Tommy’s era was built on fear and family, Duke’s era looks like it’s built on volatility—and a second-in-command can either stabilize that or weaponize it.

What Reddit theories say about Kaulo, ghosts, and “Peaky magic”

If you love the part of Peaky Blinders where realism and superstition share the same cigarette smoke, you’re going to see a lot of discussion about Kaulo—who she really is, what she wants, and how literal the “haunted” theme becomes.

A Steven Knight Reddit AMA worth bookmarking

For fans who prefer creator context (tone, intent, what the film is trying to close out), Steven Knight’s Reddit Q&A is a solid rabbit hole— especially if you’re tracking how the movie “ends an era” while still leaving the door open for more stories in this world.

Soundtrack corner: the Peaky mood in one embed

Peaky Blinders has always used music like a weapon: modern tracks clashing against period visuals to make everything feel sharper and less safe. The movie continues that tradition—so if you want to “live in the vibe” while reading cast breakdowns, start here.

Major absences (and why they matter)

Part of what makes The Immortal Man feel different is who isn’t standing beside Tommy anymore. Some characters are gone for story reasons, some for real-world casting choices, and some simply aren’t part of this wartime chapter.

Arthur Shelby: not listed among the film’s credited cast on Netflix’s title page (a big deal, given how central he was to the series).
Oswald Mosley: publicly confirmed as not returning by the actor who played him in the series.
Alfie Solomons: not officially billed in Netflix’s credited cast list, despite longtime fan hopes.
