Only Murders in the Building Season 6: Key Info
– Will take place in London rather than Arconia in New York
– Currently recording in UK, release date not confirmed
– Core cast expected to return
– Confirmed guest stars including Jennifer Saunders and Simone Ashley
– The trailer has not yet been released
When a season of Only murder in the building ends on a cliffhanger — which is every season — we can expect another to follow it. But season 6 of the Hulu and Disney+ hit show is coming to us with a huge change.
Instead of taking place in the iconic Arconia building in New York City, Oliver (Martin Short), Charles (Steve Martin) and Mabel (Selena Gomez) take 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 expect similar levels of camp mayhem.
However, there are some things we know for sure, including a stacked list of guest stars. As filming continues in the UK, here’s everything we know about it Only murder in the building season 6 so far.
Only Murders in the Building Season 6 releases window predictions
Announced on October 28, 2025, we can cross our fingers for a late 2026 release window if Season 6’s production track stays on schedule.
Since the show started in 2021, it has aired one season a year and has regularly been praised for its quick release schedule. At the time of writing, there is no indication that a new season cannot be broadcast this year.
Only Murders in the Building Season 6 Trailer: Is There One?
Don’t be silly… expect the first full trailer to arrive about four weeks before the sixth season arrives.
Only Murders in the Building Season 6 Cast and Guest Stars
We expect the following main cast members to return for Only murder 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’ve also confirmed the following new guest stars for Season 6, although we don’t know what their roles are yet:
- Jennifer Saunders
- Sean Teale
- Simon Ashley
- Amar Chadha-Patel
- Rhea Norwood
- Matthew Beard
- Sharon Horgan
Given the move from the US to the UK, there is a big 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 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 Arconia in the final scene of season 5.
Only Murders in the Building season 6 plot predictions
Naturally, the plot for Season 6 will center heavily on the group’s trip to London and Cinda’s potential death. But beyond this, we don’t really know much 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, maybe that’s what our trio will be stuck with.
Since it’s the first time Only murder in the building has ventured into international territory, anything can happen. Any question about guest stars we’ve seen between Seasons 1-5 could be picked up or dropped, and it’s likely that even more new cast members will be announced between now and Season 6’s release.
