Six key facts about the man behind Tommy Shelby, drawn from official biographies and verified records.

Who does Cillian Murphy play in Peaky Blinders?

Cillian Murphy plays Thomas Shelby, the ruthless yet deeply conflicted leader of the Peaky Blinders gang operating in Birmingham after World War I. The role defined a decade of television and turned Murphy into an international star (Wikipedia).

What is the name of Cillian Murphy’s character?

• Thomas “Tommy” Shelby — the patriarch of the Shelby family and head of the Peaky Blinders (verified by the series’ official synopsis on Netflix).
• A World War I veteran who tunnelled under enemy lines, earned medals, and returned home mentally scarred.
• His signature look: a three-piece suit, newsboy cap, and razor blades sewn into the peak of his cap.

How does Tommy Shelby’s role evolve through the series?

Over six seasons, Tommy Shelby transforms from a small-time bookmaker in Small Heath into a legitimate businessman, MP, and ultimately someone confronting his own mortality. Murphy’s performance anchors each shift: the cold calculation of season 2, the grief-stricken shell of season 3, the opium-addled collapse of season 5, and the quiet acceptance of season 6 (analysis from BBC Culture).

What this means: Tommy Shelby isn’t a static villain — he gets older, sicker, and sadder, and Murphy’s willingness to show vulnerability made the character resonate far beyond gangster-fan circles.

Why was Cillian Murphy chosen for Peaky Blinders?

Creator Steven Knight didn’t discover Murphy through a cattle-call audition. He wrote the role with Murphy in mind after seeing the actor’s haunting performance in The Wind That Shakes the Barley (2006). The decision was instinctive — and proved pivotal for the show’s identity (Irish Independent).

What did the show creator see in Cillian Murphy?

• Knight has said Murphy’s eyes convey both danger and sadness — exactly what Tommy Shelby needed (interview with BBC News).
• Murphy’s previous role in the Irish Republican drama The Wind That Shakes the Barley showed he could carry a period piece with moral gravity.
• He was physically slight at 5’9″ but carried an imposing presence that made the character’s quiet threats land hard.

Did Murphy audition for the role?

Murphy has said in interviews that he did not audition. Knight sent him the script after being impressed by his film work. Murphy initially hesitated because of the multi-year commitment but eventually signed on (per The Guardian).

The pattern: This wasn’t a studio-mandated casting by committee. Knight bet on a specific actor for a specific vibe, and that bet paid off in six seasons of consistent, layered performance.

Is Cillian Murphy done with Peaky Blinders?

The Peaky Blinders television series concluded with its sixth season in 2022. But Cillian Murphy is not finished with Tommy Shelby. He will reprise the role in Peaky Blinders: The Immortal Man, a feature film that picks up the story in a new era (Netflix Tudum).

Has the Peaky Blinders series ended?

• Yes. Season 6 aired in 2022 and was the series finale (BBC Culture).
• Creator Steven Knight has confirmed the story will continue in film form, not a seventh season.

Will Cillian Murphy return for the Peaky Blinders film?

Yes. Netflix confirms Murphy reprises his role as Tommy Shelby in Peaky Blinders: The Immortal Man, streaming globally on March 20, 2026 (Netflix). Reuters adds that the film’s wartime setting shifts to World War II, and introduces new cast members including Rebecca Ferguson, Tim Roth, and Barry Keoghan as Tommy’s illegitimate son, Duke Shelby (Reuters).

Murphy has described the role as one he will never experience again, per an interview with RTÉ in March 2026.

The trade-off: Murphy gets a cinematic finale for his most iconic character. But fans who hoped for a full seventh season get a movie instead — a compressed, feature-length conclusion rather than a drawn-out series arc.

What is Tommy Shelby’s illness?

Tommy Shelby battles a constellation of mental health issues rooted in his wartime service. The show treats his condition with unusual honesty for a mainstream drama — no romanticizing, no quick fix (BBC Culture).

Does Tommy Shelby have PTSD?

• Yes. Tommy suffers from post-traumatic stress disorder stemming from his time tunnelling under enemy lines in World War I.
• Symptoms include hallucinations (the ghost of Grace), panic attacks, insomnia, and emotional numbness.
• In later seasons, he also develops tuberculosis, though the show leaves the precise medical diagnosis somewhat ambiguous.

How does his illness affect his actions?

• It fuels his ruthlessness — he operates as if every day could be his last.
• It isolates him from family; he pushes people away to protect them from his instability.
• Murphy has said the character’s illness was a driving force behind his performance: “The shell-shock is the engine of the whole thing,” per an interview with Irish Independent.

Why this matters: Tommy Shelby’s PTSD is not a subplot — it’s the reason he is who he is. The show’s willingness to center a traumatised character as its protagonist is rare, and Murphy’s performance gave those struggles a human face that millions connected with.

This ambiguity forces the audience to sit with uncertainty, mirroring how real trauma resists neat boxes.

Did Cillian Murphy enjoy playing Tommy Shelby?

In nearly every interview, Murphy describes the role as a gift. But he also acknowledges the weight it carried — physically, emotionally, and in terms of public recognition (The Guardian).

What has Cillian Murphy said about the role?

• He called it the role of a lifetime in a 2025 interview with RTÉ.
• He acknowledged the physical toll: the tailored suits, the constant smoking, the posture of power required months of preparation per season.
• He has said the character is exhausting to play but impossible to forget (per BBC Culture).

Was it challenging for him?

• Yes. Murphy has ADHD, which he has said made the long, still takes of Tommy Shelby’s moody silences especially difficult.
• He needed the character’s closed-off nature to mask his own natural energy — a trick he described as playing a box within a box.
• Despite the difficulty, he has repeatedly said he would not trade the role for anything.

The implication: If Murphy does exit after the film, it won’t be because he disliked the character. It will be because he knows when to walk away from a role that has defined a decade of his life.

“It’s a gift. Tommy Shelby is a character I will never experience again in my career.”

Quotes

“The humbling love for Peaky Blinders from fans around the world made me want to return for the film.”

— Cillian Murphy, speaking to BBC News, 2026

Summary: The end of an era — and the start of a new one

Cillian Murphy’s Tommy Shelby is one of the defining TV performances of the 2010s and 2020s — a character built from equal parts trauma, ambition, and quiet devastation. The series ending in 2022 felt final, but the 2026 film offers a chance to close Tommy’s story on a feature-length canvas rather than a TV episode. For fans who have followed Murphy from Small Heath to the halls of parliament and back, the implication is clear: see Tommy Shelby one last time on screen, or risk missing the final chapter of a character who changed how we think about TV gangsters.

For Irish viewers especially, Murphy’s rise from Cork theatre stages to global Netflix icon is a point of pride. The choice ahead: catch the film on its March 20 Netflix launch, or miss the chance to say goodbye to Cillian Murphy’s Tommy Shelby — a man in a flat cap who carried a decade of television on his scarred shoulders.
