New additions to season 3
- Richard Dormer as Cornelius Quinn – a new Irish gangster with connections to the Wallace family (Den of Geek)
- Janet McTeer as Isobel Vaughn – a mysterious figure whose role is yet unclear (Den of Geek)
- Andrew Koji as Zeek Kimura – a hitman with “an intimate and tragic connection” to a main player (Den of Geek)
- Valene Kane – additional cast member listed on Rotten Tomatoes (role not yet specified)
Notable guest stars
Beyond the core ensemble, the season reportedly features a handful of guest appearances that add texture to the expanding conflict. The inclusion of Valene Kane, known from The Fall, suggests a substantial role, while Janet McTeer’s casting as Isobel Vaughn hints at a character who could shift the power balance. The Den of Geek article notes that Zeek Kimura (Andrew Koji) “has an intimate and tragic connection to one of the season’s main players,” pointing to a backstory that will likely drive much of the season’s emotional weight.
The expanded cast diversifies the power struggle beyond the Wallace-Dumani axis. With an Irish gangster and a Japanese hitman entering the fray, the London underworld becomes a truly multi-national chessboard. For viewers invested in the show’s gritty realism, these new faces signal that no character — old or new — is safe.
Who is the Irish guy in Gangs of London Season 3?
Irish character in season 3
The character is Cornelius Quinn, a newly introduced Irish gangster who has ties to the Wallace family’s past. According to Den of Geek, Quinn is a “new Irish character with connections to the Wallaces,” suggesting a history that predates the events of the series. His arrival injects a fresh dynamic into the already fractious alliance between the Wallace and Dumani factions.
Actor behind the Irish gangster
Cornelius Quinn is played by Richard Dormer, an actor best known for his role as Beric Dondarrion in Game of Thrones and as Sheriff Dan Anderssen in Fortitude. Dormer brings a grizzled, menacing presence to the role, as described in the Sky Atlantic cast page. He appears only in Season 3 according to Wikipedia, meaning his arc may be self-contained but impactful.
Why was Sean Wallace killed off?
Plot context of Sean’s death
Sean Wallace (Joe Cole) met his end at the conclusion of Season 2, a turning point that shattered the Wallace grip on London. While the exact details of his death are not the focus of this cast guide, the aftermath ripples through Season 3. Den of Geek confirms that “Joe Cole does not appear in season 3 except possibly in flashbacks,” making Sean’s death a permanent absence in the main timeline.
Impact on season 2 and 3
Sean’s removal forced the remaining characters to realign. Marian Wallace took a more active role, while Ed Dumani’s loyalty became increasingly ambiguous. The Sky Atlantic cast page still lists Joe Cole among the Season 3 cast, which suggests Sean appears in flashback sequences — a narrative device that keeps his legacy alive without resurrecting the character. The implication: the writers intend to explore the consequences of his death rather than reverse it.
Is Sean Wallace in season 3?
Flashbacks or hallucinations
Sean Wallace does not appear as a living character in Season 3’s primary storyline. According to Den of Geek, Joe Cole “does not appear in season 3 except possibly in flashbacks.” The Sky Atlantic cast page’s inclusion of Cole does point to his presence in some form — most likely flashback scenes intended to illuminate the past and contextualize the new Irish connection.
Sean’s absence from active cast
The absence of Sean as a living protagonist shifts the show’s centre of gravity. With Billy Wallace, Marian, and Elliot all stepping up, the power vacuum left by Sean becomes a central tension. For fans wondering whether Joe Cole will ever return in a full capacity, Wikipedia notes that Season 4 casting includes new characters but does not list Cole as a regular, though rumours of a possible return persist. As of now, no official confirmation exists.
Sean’s flashback appearances may be limited to Season 3 alone. If the show wants to bring him back fully, it will need a plot mechanism — such as a twin or a resurrection arc — that fits the show’s grounded tone. For now, treat his appearance as a memory, not a revival.
Is there a season 4 for Gangs of London?
Official announcement
Yes, Season 4 is in active development. The Wikipedia page for the series states that “filming for series 4 is underway as of October 2024,” confirming that production has moved beyond the planning stage. While no official release date has been set, the typical production timeline for the show suggests a late 2026 or early 2027 premiere.
Filming status
According to Wikipedia, the Season 4 cast includes Tamara Lawrance as Jo Malik, Luna Fujimoto as Hanaka, Eugene Nomura as Takeshi Kimura, and Melika Foroutan as Zerin. Andrew Koji’s Zeek Kimura is also set to return, bridging the seasons. The absence of Joe Cole from the regular cast list reinforces that Sean Wallace’s story is complete, though guest appearances remain possible.
Expected release
With filming already underway, a 2026 premiere for Season 4 is plausible. Fans should watch Sky Atlantic and NOW for announcements. The show has not yet been cancelled, and the momentum from Season 3’s cast additions suggests the network remains committed.

Season 3 expands the Gangs of London universe without relying on Sean Wallace as a crutch. By introducing a credible Irish gangster with deep ties to the past, the show signals a willingness to evolve beyond the Wallace family saga. For fans who crave the same brutal, character-driven storytelling, the new cast — particularly Richard Dormer’s Cornelius Quinn — offers a fresh entry point. The trade-off is clear: leave behind the familiar face of Sean Wallace, or embrace a more fragmented, unpredictable London. For committed viewers, the choice is to settle in for the long haul — because Season 4 is already being built.
