- Currently filming in the UK, release date unconfirmed
- Core cast expected to return
- Confirmed guest stars including Jennifer Saunders and Simone Ashley
- Trailer yet to be released
Whenever a season of Only Murders in the Building ends on a cliffhanger — which is every season — we can expect another to follow it. But season 6 of the hit Hulu and Disney+ show is coming to us with a huge change.
Instead of taking place at the iconic Arconia building in New York City, Oliver (Martin Short), Charles (Steve Martin) and Mabel (Selena Gomez) will be taking a trip across the pond to London, UK.
Exact details of what to expect are TBC, but if you've ever seen the episode of Murder, She Wrote where Jessica Fletcher (Angela Lansbury) went over to see her Vaudevillian cousin Emma (also Lansbury), I'm expecting similar levels of camp chaos.
There are some things we know for definite however, including a stacked roster of guest stars. As filming continues in the UK, here's everything we know about Only Murders in the Building season 6 so far.
Only Murders in the Building season 6 release window predictions
Announced on October 28, 2025, we can keep our fingers crossed for a late 2026 release window if season 6's production track stays on schedule.
Since the show began in 2021, it's aired one season per year, and has been regularly praised for its pacey release schedule. As of writing, there's nothing to suggest a new season can't air this year.
Only Murders in the Building season 6 trailer: is there one?
Don't be silly... expect the first full trailer to arrive around four weeks before the sixth season does.
Only Murders in the Building season 6 cast and guest stars
We're expecting the following main cast members to return for Only Murders in the Building season 6:
- Steve Martin as Charles-Haden Savage
- Martin Short as Oliver Putnam
- Selena Gomez as Mabel Mora
- Michael Cyril Creighton as Howard Morris
We also have the following new guest stars confirmed for season 6, though we don't know what their roles are yet:
- Jennifer Saunders
- Sean Teale
- Simone Ashley
- Amar Chadha-Patel
- Rhea Norwood
- Matthew Beard
- Sharon Horgan
Given the move from the US to the UK, there's a huge question mark surrounding the following guest stars seen in season 5:
- Renée Zellweger as Camila White
- Christoph Waltz as Bash Steed
- Bobby Cannavale as Nicky Caccimelio
- Téa Leoni as Sofia Caccimelio
- Dianne Wiest as Lorraine Coluca
- Beanie Feldstein as Althea
- Logan Lerman as Jay Pflug
- Keegan-Michael Key as Mayor Tillman
- Richard Kind as Vince Fish
- Meryl Streep as Loretta Durkin-Putnam
- Jane Lynch as Sazz Pataki
One person who we can expect to see (at least in flashback form) is Tina Fey, as her character, podcaster Cinda Canning, is found bleeding and crawling to the gates of the Arconia in the final scene of season 5.
Only Murders in the Building season 6 plot predictions
Of course, the plot for season 6 will largely center around the group's trip to London and Cinda's potential death. But other than this, we don't know a whole lot about what's to come.
Based on the season 5 finale, we know that Cinda was attacked after returning to the US to hide a woman accused of a royal murder. Who is this woman? We don't know. Is she really guilty? Well, perhaps that's what our trio will be getting stuck into.
Given that this is the first time that Only Murders in the Building has ventured into international territory, anything can happen. Any matter of guest stars we've seen between seasons 1-5 could be picked up or abandoned, and it's likely that even more new cast members could be announced between now and season 6's release.
