The hit mystery-comedy, led by Steve Martin, Martin Short, and Selena Gomez, is preparing for one of its most ambitious creative shifts yet as Season 6 moves the story across the Atlantic. After building its identity around the Arconia, the fictional New York apartment building where murder, podcasting, celebrity cameos, and unlikely friendships collided, the series is now sending Charles, Oliver, and Mabel to the U.K. for a new investigation.
The latest update makes that international move feel even bigger. Season 6 has added a major group of recurring guest stars, including David Tennant, Nicola Coughlan, Jodie Whittaker, Jim Broadbent, Adrian Lukis, Richard Ayoade, and Kathryn Hunter. It is a cast expansion that immediately signals a season shaped by British television, stage, comedy, fantasy, and prestige drama traditions.
For viewers searching for “Only Murders in the Building STV,” the key point is that the new season is currently framed around the show’s London-set story and its expanding U.K.-based ensemble. The provided information identifies Hulu as the show’s platform and confirms that Season 6 is currently in production in the U.K.; it does not confirm any separate STV broadcast arrangement.
The London Move Changes the Show’s Rhythm
The central trio — Charles, Oliver, and Mabel — has always worked because of contrast. Charles is cautious and theatrical in his own restrained way. Oliver is flamboyant, impulsive, and emotionally expansive. Mabel is sharper, younger, and more grounded, often cutting through the absurdity around her. Their chemistry has powered the show through multiple murder investigations while allowing the series to play with true crime culture, old Hollywood, Broadway drama, podcasting fame, and New York eccentricity.
Season 6 raises the stakes by placing that chemistry in a new environment. Production is currently underway in the U.K., and the story follows the trio as they leave New York City to investigate London’s newest mystery. The shift marks the first time the comedy mystery series has ventured outside of the U.S., a major change for a show whose identity has been closely tied to its apartment-building setting.
The new case continues the story that began in the Season 5 finale, with Charles, Oliver, and Mabel investigating the death of Cinda Canning, played by Tina Fey. Cinda has long been connected to the show’s fascination with podcasting, ambition, rivalry, and the blurry line between solving crimes and turning them into entertainment. Her death gives Season 6 a narrative bridge between the familiar world of the earlier seasons and the new London setting.
A Guest Cast Built for Suspicion
The most striking part of the latest Season 6 news is the scale and quality of the guest cast. David Tennant, Nicola Coughlan, Jodie Whittaker, Jim Broadbent, Adrian Lukis, Richard Ayoade, and Kathryn Hunter will appear in recurring guest star roles.
As is usually the case with Only Murders in the Building, exact character details are being kept under wraps. That secrecy matters. The series is built around suspicion, misdirection, eccentric personalities, and the pleasure of watching famous faces become potential suspects, witnesses, accomplices, or comic distractions.
David Tennant arrives with an enormous television profile, best known for Doctor Who and Rivals. Jodie Whittaker, also strongly associated with Doctor Who and known for Broadchurch, adds another major British screen presence. Their inclusion immediately gives Season 6 a playful connection to British genre television, particularly for viewers familiar with their separate histories as Doctors.
Nicola Coughlan brings the popularity of Bridgerton and Derry Girls, giving the season a performer known for both sharp comic timing and emotional range. Jim Broadbent adds veteran prestige, with credits including Moulin Rouge and Bridget Jones’ Diary. Richard Ayoade, widely known for The IT Crowd and Garth Marenghi’s Darkplace, brings a distinctive comic style that seems especially compatible with the show’s dry, self-aware humor.
Kathryn Hunter, whose credits include The Tragedy of Macbeth and Poor Things, adds a more theatrical and unpredictable energy. Adrian Lukis, known for The Crown and The War Between the Land and the Sea, rounds out the newly announced group.
Together, the additions make Season 6 feel less like a normal guest-star rotation and more like a deliberate transformation of the show’s world.
The Returning Core Still Matters Most
Even with the new names, the emotional center remains Steve Martin, Martin Short, and Selena Gomez.
The show works because Charles, Oliver, and Mabel are not conventional detectives. They are amateurs whose instincts are shaped as much by loneliness, curiosity, friendship, ego, and media obsession as by evidence. Every season has used the murder mystery structure to explore something larger: aging, reinvention, fame, grief, artistic failure, and the complicated intimacy of people who become a chosen family through crisis.
Season 6’s London setting could test that dynamic in fresh ways. The trio will be outsiders in a different cultural environment, potentially surrounded by new rules, new social codes, and a suspect pool filled with characters who may understand the city far better than they do.
Michael Cyril Creighton is also part of the Season 6 cast, returning as Howard Morris. His presence helps preserve continuity with the world of the Arconia, even as the show expands beyond New York.
Da’Vine Joy Randolph has also been seen on set for Season 6, but whether or not she is returning to the show has yet to be officially confirmed. That distinction is important: a set appearance may suggest involvement, but it is not the same as an official casting announcement.
A Massive Ensemble Suggests a Dense Mystery
The newly announced stars are not the only fresh faces joining the season. Season 6 also includes new recurring guest stars Martin Freeman, Geri Halliwell-Horner, Jamie Demetriou, Anjana Vasan, Jane Horrocks, Derek Jacobi, Lesley Nicol, Jennifer Saunders, Sean Teale, Simone Ashley, Amar Chadha-Patel, Rhea Norwood, Matthew Beard, and Sharon Horgan.
That is a remarkably broad ensemble. It includes performers associated with British comedy, prestige drama, period television, pop culture, and international streaming hits. In practical terms, it gives the writers a large number of possible suspects and narrative pathways.
For Only Murders in the Building, that kind of casting is not just decoration. Guest stars often function as clues. The show uses recognizable actors to play with audience expectations: a beloved comic figure can become suspicious; a dramatic actor can become absurd; a seemingly minor character can suddenly become central to the case.
The London season appears designed around that same formula, only on a larger and more international scale.
Why the British Casting Makes Creative Sense
Moving the show to London creates an opportunity to draw from a different mystery tradition. The series has always been influenced by classic whodunits, theatrical staging, and puzzle-box storytelling. London, with its deep connection to detective fiction, stage performance, literary crime stories, and prestige television, is a natural extension of that identity.
The casting reinforces that direction. Tennant and Whittaker bring genre credibility. Broadbent and Jacobi bring classical weight. Ayoade, Saunders, Horrocks, Demetriou, and Horgan bring different shades of British and Irish comedy. Coughlan and Ashley connect the show to a younger international streaming audience.
The result is a season that appears positioned to blend American true-crime satire with British murder-mystery tradition. That combination could refresh the series without abandoning what made it popular in the first place.
The Creative Team Behind the Expansion
Only Murders in the Building hails from co-creators and writers Martin and John Hoffman. Hoffman and Martin are executive producers along with Short, Gomez, Dan Fogelman, Jess Rosenthal, Ben Smith, Jennifer Crittenden & Gabrielle Allan. 20th Television is the studio.
That creative continuity is significant. A major location shift can sometimes make a long-running series feel like a different show. Here, the production appears to be balancing change with stability: the setting and guest cast are expanding, but the central creative architecture remains intact.
The show’s success has always depended on tone. It must be funny without weakening the murder mystery, emotional without becoming sentimental, and self-aware without collapsing into parody. Maintaining that balance in a London-set season will be one of Season 6’s biggest creative tests.
What the New Season Could Mean for the Franchise
Season 6 may become a defining chapter for the series because it tests whether Only Murders in the Building can survive beyond its original premise. The title itself suggests confinement: one building, one community, one recurring site of crime. By taking the trio overseas, the show is stretching that concept.
That could be risky, but it may also be necessary. After multiple seasons centered on the Arconia and its extended orbit, a new location offers fresh visual language, new character types, and a broader storytelling canvas. It also allows the show to deepen its global appeal by leaning into British talent and London-based intrigue.
For Hulu and Disney’s broader streaming strategy, a season like this also makes sense. A U.K.-set installment with globally recognizable stars gives the show a stronger international profile. Actors such as Tennant, Coughlan, Whittaker, Broadbent, Freeman, Ashley, Horgan, and Saunders carry appeal across multiple markets.
Why Fans Are Paying Close Attention
The excitement around Season 6 is not only about celebrity casting. It is about possibility.
Fans want to know how the show will justify leaving the Arconia. They want to know how Cinda Canning’s death connects to London. They want to know whether the show can preserve its intimate charm while operating on a much larger stage. They also want to know which of the many guest stars will be comic relief, which will be suspects, and which may turn out to be more important than they first appear.
The secrecy around character details only adds to that anticipation. In a mystery-comedy, withholding information is part of the marketing. Every casting announcement becomes a clue, or at least an invitation to speculate.
Conclusion: A Bold New Chapter for a Still-Evolving Hit
Only Murders in the Building Season 6 is shaping up as one of the show’s most ambitious seasons yet. By moving the investigation to London and surrounding Steve Martin, Martin Short, and Selena Gomez with an unusually deep roster of British and international talent, the series is clearly aiming for more than a routine continuation.
The latest cast additions — David Tennant, Nicola Coughlan, Jodie Whittaker, Jim Broadbent, Adrian Lukis, Richard Ayoade, and Kathryn Hunter — give the new season immediate prestige and comic potential. Combined with previously announced guest stars and the returning core trio, Season 6 has the ingredients for a dense, playful, and culturally distinctive mystery.
The challenge will be maintaining the heart of the series while expanding its world. If the show succeeds, the London season could prove that Only Murders in the Building is not limited by geography. It may have started in one New York building, but its next great mystery is ready to cross borders.
