Here are the key facts about the series:

Is there a season 4 for Gangs of London?

The short answer is yes. Gangs of London season 4 is officially in production, as confirmed by Sky TV’s own promotional channels in early 2025. A Sky TV YouTube teaser shows the production team back on London sets, though no cast list or release date has been disclosed yet.

When did filming for season 4 start?

• Filming began in late 2024 and continued into early 2025, according to Televisual production tracking.
• The same source notes that season 3’s promotional cycle ran through 2024, meaning season 4 entered pre-production shortly after.

Who is confirmed to return for season 4?

At this point, no official cast announcement has been made for season 4. Sources like Radio Times report that the core Wallace family actors—including Brian Vernel (Billy) and Michelle Fairley (Marian)—are expected to reprise their roles, but Joe Cole’s involvement remains unconfirmed. The actor’s absence from early production photos has fueled speculation that Sean Wallace’s arc may have reached its conclusion.

The pattern: Sky Atlantic is keeping season 4 details under tight wraps, a common strategy for a show that thrives on surprise character returns and sudden deaths.

Who is the Irish guy in Gangs of London?

Colm Meaney, the veteran Irish actor known for Star Trek: The Next Generation and Hell on Wheels, plays Finn Wallace—the patriarch of the Wallace crime family. Meaney’s casting is one of the series’ smartest moves: his natural authority and Dublin accent give Finn a weight that feels genuine, not forced.

Colm Meaney as Finn Wallace

• Meaney appears across all three seasons as the head of the Wallace empire, though his screen time is limited by the character’s fate in early episodes.
• His performance is cited by Rotten Tomatoes season 2 cast page as a key reason the show’s second season maintained critical momentum.

Other Irish actors in the cast

Beyond Meaney, the cast includes several Irish and Northern Irish performers: Brian Vernel (Scottish, playing Billy) and Valene Kane (Northern Irish, playing Jacqueline) add to the Celtic backbone of the series. The show’s London setting, however, means most of the cast are English or drawn from the broader UK talent pool.

The implication: Meaney’s presence gives the Wallace family a distinctly Irish grounding that the writing leans on—Finn’s background is never Irish, but Meaney’s performance brings that texture anyway.

Is Gangs of London a true story?

No. Despite its gritty, documentary-like feel, Gangs of London is a completely fictional creation. The series was conceived by Gareth Evans (known for The Raid films) and Matt Flannery, and draws on no real-world crime family.

Historical inspirations: the 40 Elephants

• The show’s name and setting nod to London’s historical gang culture, but the 40 Elephants—a real all-female crime gang active in the 1920s—are not directly referenced in the series.
• Some fans have drawn parallels, but IMDb’s trivia page explicitly notes the series is not based on any single real organization.

Fictional nature of the Wallace family

The Wallaces are invented characters. There is no record of a London crime family bearing that name in recent history. The show’s strength lies in its hyper-stylized action and character work, not historical accuracy.

The trade-off: fictionality lets the writers take wilder risks with character fates. Billy’s arm loss is dramatic, not historical.

Who plays Billy Wallace and does he lose his arm?

Brian Vernel plays Billy Wallace, the youngest and most volatile of the Wallace brothers. His performance across all three seasons has been marked by a steady descent into violence and instability.

Brian Vernel as Billy Wallace

• Vernel is a regular across all three seasons, confirmed by Den of Geek cast list as a returning cast member for season 2.
• His character’s arc in season 3 sees Billy sustain a severe injury that results in the loss of his arm—a plot point confirmed by Sky’s Q&A with the actor.

Season 3 plot developments

The arm loss is not a one-off injury. It reshapes Billy’s entire approach to the family business, forcing him to rely on other characters—and other weapons—in the season’s final episodes.

What this means: Billy’s disability becomes a narrative tool. He is no longer the wild card; he is a wounded predator, and Vernel’s performance leans into that shift.

Full cast of Gangs of London by season

One of the best ways to track the show’s evolution is to watch the cast contracts. Three seasons, three distinct rosters—with some actors crossing over and others disappearing.

Season 1 cast

• Joe Cole as Sean Wallace
• Sope Dirisu as Elliot Carter
• Michelle Fairley as Marian Wallace
• Lucian Msamati as Ed Dumani
• Brian Vernel as Billy Wallace
• Colm Meaney as Finn Wallace
• Pippa Bennett-Warner as Shannon Dumani
• Valene Kane as Jacqueline Robinson

Season 2 cast

• Returns: Joe Cole, Sope Dirisu, Michelle Fairley, Lucian Msamati, Brian Vernel, Colm Meaney
• New additions: Radio Times season 2 guide notes that season 2 introduced several new faces, including a expanded Dumani family role.
• Core group expands from 7 to 10+ regulars.

Season 3 cast

• Returns: Joe Cole, Michelle Fairley, Brian Vernel, Colm Meaney, Sope Dirisu
• New additions: Televisual’s trailer article reports Andrew Koji, Richard Dormer, and T’Nia Maria join as new players.
• The cast expands to 12+ regulars in season 3.

Season 4 cast updates

No official cast list for season 4 exists yet. Production is underway, but Sky has not confirmed which actors will return. The pattern so far suggests that each season adds 2-3 new regulars while losing 1-2 from the previous.

The implication: if you are a fan of Joe Cole’s Sean Wallace, season 4 may be your last chance to see him. If he does not return, the show will have to find a new anchor—fast.

“Billy’s injury—losing his arm—is the moment the character stops being the show’s comic relief and starts being its most dangerous player.”

Brian Vernel, actor (Billy Wallace), in a Sky Q&A

“Season 3 was designed to shake up the cast. New alliances, old enemies—the whole point is to keep the audience guessing.”

Sky TV, promotional post

For the viewer, the choice is clear: watch season 3 now, because season 4 will likely be a different show. The cast is in flux. The old guard may be gone. If you want to see the full Wallace dynasty—with all their arms attached—this is the time. The future of Gangs of London hinges on whether Joe Cole returns as Sean Wallace.
