The sixth season of 'Only Murders in the Building' is assembling an impressive ensemble of British and Irish talent as the Hulu mystery comedy relocates its central investigation to London. Steve Martin, Martin Short, and Selena Gomez will reprise their roles as Charles-Haden Savage, Oliver Putnam, and Mabel Mora. The amateur sleuths depart New York following a deadly cliffhanger that unveils a case connected to England. Production is currently underway in the United Kingdom, though Hulu has yet to announce a release date.
Season 6 Cast Expands
According to The TV Cave, the recurring guest cast has now swelled to 20 actors. Deadline confirmed that David Tennant, Jodie Whittaker, Nicola Coughlan, Jim Broadbent, Richard Ayoade, Adrian Lukis, and Kathryn Hunter have joined the upcoming season. This latest round of additions unites two former 'Doctor Who' leads, Tennant and Whittaker, while Coughlan and Simone Ashley bring together two stars from 'Bridgerton'.
Other confirmed guest stars include Jennifer Saunders, Martin Freeman, Jamie Demetriou, Sharon Horgan, Derek Jacobi, Geri Halliwell-Horner, Anjana Vasan, Jane Horrocks, Lesley Nicol, Sean Teale, Amar Chadha-Patel, and Rhea Norwood. Details about their characters and connections to the murder remain under wraps. Michael Cyril Creighton will return as Howard Morris, while Da'Vine Joy Randolph is expected to reprise her role as Detective Donna Williams and follow the trio across the Atlantic.
London Mystery Follows Cinda Canning's Cliffhanger
Season 5 concluded with rival true-crime podcaster Cinda Canning, portrayed by Tina Fey, becoming the apparent victim of the show's next murder. Her final storyline contained clues linked to England, prompting Charles, Oliver, and Mabel to take their investigation overseas. The sixth season will consist of 10 episodes and shift much of the action away from the Arconia, the Manhattan apartment building central to the first five seasons. London will serve as the primary production base for the upcoming case.
Tina Fey is set to appear again despite Cinda's fate, though the series has not revealed whether the character will feature through flashbacks or another narrative device. Hulu renewed 'Only Murders in the Building' for a sixth season after the fifth-season finale in October 2025. Filming began in London in May 2026. All five completed seasons are available to stream on Hulu in the United States and Disney Plus in several international markets.
