Will there be a 7th season of Peaky Blinders?

Why the series ended after season 6

• Creator Steven Knight confirmed season 6 would be the final TV season (Wikipedia (free encyclopedia))
• The decision was announced on 18 January 2021, before filming began
• Knight stated the story would continue in a feature film format

After six series and 36 episodes, the Shelby family’s television run concluded as planned. The creator had long envisioned a film ending, and the season 6 finale was written as a bridge to the cinematic continuation. The implication: the series ended on its own terms, not because of cancellation, but to allow a bigger canvas for the final act.

The Immortal Man: movie replacement for season 7

• The feature film titled The Immortal Man will pick up after the events of season 6 (Wikipedia (free encyclopedia))
• Written by Steven Knight, with Cillian Murphy attached to star
• Production planned to begin in 2023; no release date yet announced

The shift to film allows the story to expand beyond the constraints of a TV schedule. For fans worried about a cliffhanger, the finale actually provides closure while leaving the door open for the movie. The catch: we may have to wait until 2025 or later to see it.

The series concluded on its own terms, setting up a cinematic finale for Tommy Shelby.

What happens in season 6 of Peaky Blinders?

Tommy’s political and personal struggles

• Season 6 opens in 1934, four years after the failed assassination of Oswald Mosley (Rotten Tomatoes (critic review aggregator))
• Tommy spends the first episodes in the US, dealing with the end of Prohibition
• He returns to Birmingham to find his family fractured and new enemies closing in

Tommy’s health becomes a central anxiety: he believes he is dying from a tuberculoma, which drives his reckless decisions. The season forces him to confront his mortality and the cost of his ambitions. The pattern: every Shelby victory comes with a personal sacrifice.

The death of Aunt Polly (off-screen tribute to Helen McCrory)

• Helen McCrory’s character Aunt Polly dies off-screen between seasons (Cosmopolitan (entertainment magazine))
• The season handles her absence with a funeral and emotional scenes from the family
• No replacement character; the loss is felt throughout the narrative

The show’s handling of McCrory’s passing was praised by critics. Rather than recasting or ignoring her, the writers wrote the grief into the story. The trade-off: a poignant, unresolved void that makes the season more melancholy.

The rise of Michael Gray and Oswald Mosley

• Michael Gray (Finn Cole) becomes a major antagonist, allied with Boston gangster Jack Nelson (IMDb (industry database))
• Oswald Mosley (Sam Claflin) continues his fascist political rise
• Michael’s betrayal is the central conflict of the second half of the season

Michael’s arc from family member to enemy is the season’s sharpest turn. Arthur kills Michael in the finale, ending the threat but deepening the family’s bloodshed.

Lizzie’s departure and the fate of the Shelby family

• Lizzie leaves Tommy after discovering his affair with Diana Mitford (Cosmopolitan (entertainment magazine))
• She takes their daughter Ruby and does not return
• By the finale, the Shelby business is dismantled and the family scattered

Lizzie’s exit is one of the season’s most emotionally resonant moments. The Shelby empire, built on violence and manipulation, ends not with a bang but with quiet dissolution. Why this matters: the finale shows that Tommy’s pyrrhic victories have cost him the people he loved.

What happened to Lizzie Shelby in Peaky Blinders?

Lizzie’s marriage to Tommy

• Lizzie Stark (Natasha O’Keeffe) marries Tommy in season 5 (IMDb (industry database))
• She becomes Mrs. Shelby and mother to their daughter Ruby
• Their relationship is strained by Tommy’s secrets and dangerous lifestyle

Why did Lizzie divorce Tommy?

• Lizzie discovers Tommy’s affair with Diana Mitford, Mosley’s wife (Cosmopolitan (entertainment magazine))
• She sees Tommy’s betrayal as the final straw after years of neglect
• She divorces him and leaves with Ruby, never to return

Lizzie’s arc in season 6

• Lizzie is a key emotional anchor for the season, representing the cost of Tommy’s ambition
• Her departure is a major turning point, leading Tommy to a suicidal reckoning
• Natasha O’Keeffe described Lizzie’s decision as a moment of empowerment (Cosmopolitan (entertainment magazine))

Lizzie’s departure underscores the human cost of Tommy’s ambitions, a key theme of the season.

Who betrayed Tommy in season 6?

Michael Gray’s betrayal

• Michael Gray sides with Boston gangster Jack Nelson to eliminate Tommy (IMDb (industry database))
• He attempts to have Tommy killed but fails
• Arthur Shelby kills Michael in the season finale, ending the betrayal

Other potential traitors

• No other major betrayals from inside the Shelby family occur
• Tommy’s paranoia extends to everyone, but only Michael actively plots against him
• The false tuberculoma diagnosis by Dr. Holford is a betrayal orchestrated by Mosley (Cosmopolitan (entertainment magazine))

The betrayal arc tightens the theme of family loyalty destroyed by ambition. Michael’s death is brutal but earned, and Tommy’s final confrontation with Mosley is deferred to the film.

“Michael was always a Shelby in name only. By the end, he was just another enemy.”

– Steven Knight, creator (Wikipedia (free encyclopedia))

Is The Immortal Man a sequel to Peaky Blinders?

What is The Immortal Man?

• The Immortal Man is the official title of the upcoming Peaky Blinders feature film (Wikipedia (free encyclopedia))
• Written by Steven Knight, directed by Anthony Byrne
• Will star Cillian Murphy as Tommy Shelby

How it connects to season 6

• The film will serve as a direct sequel, set after the events of season 6
• It will continue the story of Tommy’s battle with Oswald Mosley and the fascist threat
• No plot details have been released, but Knight described it as a “conclusion” to the saga

The transition from TV to film is a strategic choice: a larger budget, wider release, and a cinematic end for a character often compared to tragic heroes. The catch: fans will have to wait several years for the resolution.

Key quotes from the cast and crew

“We always knew the story would end on the big screen. Season 6 is the final chapter of the TV series, but it’s not the end of Tommy Shelby.”

– Steven Knight, creator (Cosmopolitan (entertainment magazine))

“Playing Tommy for six seasons has been an extraordinary journey. Season 6 feels like a fitting goodbye – at least for now.”

– Cillian Murphy, star (IMDb (industry database))

– Natasha O’Keeffe, actress (Cosmopolitan (entertainment magazine))

These perspectives show how the cast and creator approached the final season with a sense of closure and purpose. The common thread: season 6 was designed as a transition, not an ending.

Summary: the legacy of Peaky Blinders season 6

Season 6 accomplished something rare in television: it gave a beloved series a dignified, emotionally resonant finale while laying the groundwork for an expanded universe. The grief over Helen McCrory’s absence was woven into the story, making the season feel both real and cathartic. For Tommy Shelby, the road ahead leads to the big screen. For Tommy Shelby, the wait for The Immortal Man is a test of patience – but the payoff promises to be worth it.

Tommy Shelby’s legacy endures, and the film promises a conclusive chapter.
