‘Only Murders in the Building’ Season 6 Just Assembled the Most Exciting British Cast on Television
Few American shows have made a habit of luring A-list guest talent quite like ‘Only Murders in the Building’. Since its Hulu debut, the comedy-mystery has become a revolving door of prestige names, drawing everyone from Meryl Streep to Christoph Waltz into its orbit. For its sixth season, the series is doing something it has never done before, sending its trio of amateur sleuths across the Atlantic to London, and it appears the show has absolutely no intention of arriving quietly.
Filming is already underway in the UK, marking the first time the show has ventured overseas, and the casting announcements have been rolling out at a rapid pace. The season will see crime-solving trio Steve Martin, Martin Short, and Selena Gomez return as Charles, Oliver, and Mabel, continuing their investigation into the death of Cinda Canning, a thread left dangling by the Season 5 finale. Da’Vine Joy Randolph has also been pictured in social media posts from set, though her return has not yet been officially confirmed.
Now, in an exclusive report by Variety, eight additional recurring guest stars have been revealed, and the list reads like a who’s who of acclaimed British and Irish talent. Joining the season are Martin Freeman, Geri Halliwell-Horner, Jamie Demetriou, Anjana Vasan, Jane Horrocks, Derek Jacobi, and Lesley Nicol, an ensemble that spans beloved British sitcoms, Oscar-winning films, and globally recognized pop culture. As is usually the case with the show, exact character details for the new additions are being kept under wraps.
The additions build on a wave of casting news that broke just a day earlier. Disney confirmed that Jennifer Saunders, Sean Teale, Simone Ashley, Amar Chadha-Patel, Rhea Norwood, Matthew Beard, and Sharon Horgan had already been set in recurring guest roles for the season.
The show has historically used its guest stars as full dramatic participants rather than narrative set dressing, which makes an ensemble including the star of ‘Bridgerton’, the creator of ‘Bad Sisters’, and the legend behind ‘Absolutely Fabulous’ feel genuinely exciting rather than merely decorative.
Returning star Michael Cyril Creighton is also back, and ‘Only Murders in the Building’ hails from co-creators and writers Steve Martin and John Hoffman, with both serving as executive producers alongside Martin Short, Selena Gomez, Dan Fogelman, and Jess Rosenthal, among others.
20th Television serves as the studio behind the production. Should the season stay on its current production schedule, a late 2026 release window remains on the table, though no premiere date has been confirmed.
With a roster now stretching across generations of British entertainment history, from Derek Jacobi’s theatre royalty to Jamie Demetriou’s cult comedy following, the show seems determined to make its London chapter its most ambitious yet.
Whether the trio can crack a British mystery as cleverly as they handled the Arconia is the question fans will be debating until the first trailer drops, so share your thoughts below on which of these new cast members you are most excited to see step into the world of the podcast-obsessed detectives.
