For the past four years, Hulu's cozy murder-comedy Only Murders in the Building has been a staple of fall TV. In season 5, the murder-mystery series about true-crime podcasters Charles (Steve Martin), Oliver (Martin Short), and Mabel (Selena Gomez) returned to its roots with a season centered on their pre-war building, The Arconia, and its faithful late doorman Lester (and the secret mob-run casino under the basement).
Now that Lester's killer has been found, it's time for OMITB to expand beyond the building once again. With the series officially renewed for another installment, it's time to go over everything we know about Only Murders in the Building season 6 so far.
Everything We Know About 'Only Murders in the Building' Season 6
When will 'Only Murders in the Building' season 6 come out?
On October 28, 2025, Hulu renewed its Emmy-winning comedy on the same day as its season 5 finale. Though the streamer hasn't unveiled a release date, OMITB has a regular spot on fans' TV calendars. Thus far, every season has aired between August and October (besides season 2, which debuted in June 2022). Considering filming began in May 2026 and is still ongoing in August, late fall toward the end of the year seems most likely.
In the meantime, Hulu has blessed fans with ample behind-the-scenes photos of the stars enjoying life across the pond to hold us over.
Who will be in the cast of 'Only Murders in the Building' season 6?
In addition to the essential main trio of Steven Martin (Charles Haden-Savage), Martin Short (Oliver Putnam), and Selena Gomez (Mabel Mora), we know that Michael Cyril Creighton (Howard Morris) and Da'Vine Joy Randolph (Detective Williams) will return. (When the series began filming in London in May 2026, its official Instagram account shared a selfie taken by showrunner John Hoffman, our funny throuple, and Randolph.)
Meryl Streep seems to have had a blast starring opposite her real-life beau Short as his on-screen wife, Loretta Durkin-Putnam, and she's keeping the good times rolling. The Oscar winner has appeared in photos shared by Gomez and the series' official accounts, so you can count on seeing more of her.
It's yet to be formally announced, but there's also a high chance we'll see more of Jackie Hoffman (Uma Heller). OMITB could also find another way to bring back Paul Rudd, who voiced the robot LESTR in season 5 and seems to love returning to the murder mystery in some form.
As it turns out, one of the series' recurring guest stars is set to return as season 6's murder victim. Tina Fey will reprise her role as Cinda Canning, rival podcaster to our favorite trio since season 1 (not to mention the initial inspiration for their pod). In the final scenes of season 5, set three months after Lester's case was solved, Charles, Mabel, and Oliver sit down to listen to Cinda's new podcast about a curly-haired woman suspected of killing a royal descendant, whom Cinda "sent to America" for safety. Soon after, they come upon the same woman as she lies dying at the Arconia's front gate...and she turns out to be Cinda.
Who are the guest stars in 'Only Murders in the Building' season 6?
In June 2026, Hulu began unveiling its huge slate of guest stars joining season 6. As per usual, their roles are being kept under wraps, but it seems the cozy mystery is rounding out its slate of suspects with as many famous Brits and Irish stars as it can wrangle across the pond. Here's who is joining the ensemble: David Tennant, the actor most associated with Doctor Who, as well as another Doctor Who alum, Jodie Whittaker (Whittaker played the 13th Doctor, while Tennant played the 10th and 14th), comedian/showrunner Sharon Horgan (Bad Sisters, Catastrophe), Bridgerton breakouts Nicola Coughlan and Simone Ashley, comedian/writer Richard Ayoade (The IT Crowd), British TV staple Adrian Lukis (Judge John Deed, Pride and Prejudice), Martin Freeman (The Office, Sherlock), thee Ginger Spice, Geri Halliwell-Horner, comedian/writer Jamie Demetriou (Stath Lets Flat), Downton Abbey alum Lesley Nicol, stage actress/We Are Lady Parts star Anjana Vasan, both Jane Horrocks and Jennifer Saunders from Absolutely Fabulous, Skins star Sean Teale, Jim Broadbent (the Paddington and Harry Potter movies), Amar Chadha-Patel (Willow), Rhea Norwood (Heartstopper), Matthew Beard (Vienna Blood), and acclaimed thespians Kathryn Hunter and Derek Jacobi. And if you looked at that list and thought, "I wonder if we could use yet another Doctor Who?" You'd be onto something because the OMITB showrunner clearly felt the same and added Peter Capaldi to the cast. The 12th Doctor's casting was reported in August.
Whoa! It's safe to say that the British (and the Irish!) are coming—and this season might just be bigger than ever!

But don't hold your breath! Another major star was announced in late August—and with a special announcement, no less. The official TikTok and Instagram accounts dropped a wholesome clip of Gomez standing alongside Streep on set, teasing, "We have had so many amazing guest stars for Only Murders in London," to which Streep adds, "Yeah, but we’re just missing one." While Short jokingly makes an entrance, Olivia Colman comes into the shot, looking adorable in period garb. (Streep is also in costume; could this mean Colman is playing someone in her latest theater production? Or perhaps some historical reenactment actor?) The word is still out on whether she'll reunite on screen with her former Broadchurch co-stars David Tennant and Jodie Whittaker, but her quirky sense of humor seems like the perfect fit for the London-set season!
Where will 'Only Murders in the Building' season 6 take place?
Only Murders in the Building is headed to jolly old London! Following the Cinda finale cliffhanger, Hulu confirmed that season 6 will film in London as Charles, Oliver, and Mabel unfurl the truth behind Cinda's murder.
While the show briefly pops over to L.A. in season 4, there's a chance that season 6 will be set in London for the majority of its run. Since Cinda's death stretches the definition of "in the building"—Cinda even grasps at the gate in her final moments to make sure that she counts—the trio may only be able to investigate from across the pond. Fans will have to wait and see how much of season 6 will actually take place in the building.
What will 'Only Murders in the Building' season 6 be about?
I have so many questions about season 6 after that cliffhanger. Who is the "royal descendant" who was murdered? How much of Cinda's new podcast, "The Girl With the Curls," did she record before fleeing to the Arconia to, presumably, get help from our trio? Is Cinda herself the girl with the curls, and she made a podcast referring to herself in the third person? Or was she killed while posing as a decoy, and the titular girl is still out there?
In an interview with The Hollywood Reporter, co-creator John Hoffman shared that, after season 5's Arconia-centered plot, season 6 will center on Cinda as another "origin point" for the trio. It'll also explore the classic detective literature that gave birth to murder-mystery storytelling.
The showrunner told the outlet, "[Season 6] all came together as wanting to look at origins for both the storytelling nature of what is at the source [of the detective genre] through the Agatha Christies and Arthur Conan Doyles and on and on, and on to podcasting today and that line between them, and what that might hold as fertile ground for next season beyond the incredible character that Tina Fey created for us that got this ball rolling."
"With Cinda, we have someone in the lexicon of the show who is the beginning of the legacy for our trio," he explained. "How does that extend further for the legacy of this endeavor of storytelling within this realm of murder mystery? All of that felt steeped in great history for the show and this kind of storytelling. I’m insanely stoked about an extra charge behind the ideas and the writing while also keeping very, very central who this trio is and where they come from, but being able to supercharge the season next year with some really new elements that feel well-timed."
