Only Murders Season 6 guest cast : full reveal

Seven new faces are heading to London for season 6 of Only Murders in the Building. Disney officially confirmed the guest cast lineup on June 10, 2026, and the names attached to this new chapter are genuinely worth paying attention to. We've been tracking this one closely, and the announcement delivers more than expected.

A London chapter with a seriously stacked guest cast

The sixth season marks a significant shift for the show : the trio leaves New York City behind to tackle a brand-new mystery set in London. Steve Martin, Martin Short, and Selena Gomez all return as the beloved crime-obsessed podcasters, and they're bringing some serious company with them.

On the returning side, the roster already reads like an awards season shortlist. Meryl Streep and Da'Vine Joy Randolph are back, alongside Richard Kind, Nathan Lane, Bobby Cannavale, Renée Zellweger, Christoph Waltz, Téa Leoni, Keegan-Michael Key, Beanie Feldstein, Dianne Wiest, Jermaine Fowler, Logan Lerman, and Michael Cyril Creighton. That's not a supporting cast, that's a small film festival.

But the fresh additions are what make this season particularly interesting from a casting perspective. Disney confirmed seven new names joining the ensemble :

• Jennifer Saunders (Absolutely Fabulous)
• Sean Teale (Skins)
• Simone Ashley (Bridgerton)
• Amar Chadha-Patel (Willow)
• Rhea Norwood (Heartstopper)
• Matthew Beard (The Imitation Game)
• Sharon Horgan (Bad Sisters)

The choice to anchor the London storyline with predominantly British talent isn't just logical, it's smart. Jennifer Saunders brings decades of sharp comedic credibility. Sharon Horgan, fresh off her acclaimed run on Bad Sisters, adds a darker comic edge that could fit this show's tone perfectly. And Simone Ashley's crossover from Shondaland territory to a Hulu mystery is the kind of casting move that gets people talking. For those following cast announcements across platforms, Anwar Aroussi joining the Bridgerton season 5 cast shows just how active this wave of transatlantic casting has become in 2026.

Production details and where to stream previous seasons

Only Murders in the Building was co-created by Steve Martin and John Hoffman, the latter known for his work on Grace & Frankie and Looking. The show has been produced by 20th Television throughout its run, and season 6 will follow the same 10-episode format as previous seasons.

The executive producer lineup for season 5 included John Hoffman, Steve Martin, Martin Short, Selena Gomez, Dan Fogelman, Jess Rosenthal, Ben Smith, and JJ Philbin. It's reasonable to expect continuity in that creative structure for the new season.

At the time of writing, Disney hasn't dropped a release date or shared any plot details for season 6. The move to London is confirmed, but beyond that, the story remains under wraps. Given the show's habit of keeping its mysteries close, that's not surprising. We'll update our listings the moment a premiere date is announced.

All five previous seasons of Only Murders in the Building are currently available to stream. In the United States, they're on Hulu and accessible through the Hulu on Disney+ bundle. Internationally, Disney+ carries all five seasons for subscribers outside the US. If you want to catch up before season 6 lands, that's roughly 50 episodes of television to get through.

Why the London move could redefine the show's format

Relocating a series that's been so tightly tied to a single building and a specific New York City identity is a genuine creative risk. Only Murders in the Building built its entire brand around the Arconia, its residents, and the claustrophobic intimacy of Manhattan apartment life. Pulling the trio out of that setting and dropping them into London with a largely British guest cast changes the dynamic in ways we haven't seen from this show before.

The casting choices suggest the writers are leaning into that disruption rather than softening it. Jennifer Saunders and Sharon Horgan both have strong comedic DNA rooted in British culture, which could create genuine friction and chemistry with Martin and Short's very American energy. That clash of comedic sensibilities could either be the season's greatest strength or its biggest challenge.

Rhea Norwood and Sean Teale bring younger, more contemporary energy to a cast that traditionally skews older. Amar Chadha-Patel and Matthew Beard fill out a well-rounded British ensemble that feels deliberately curated rather than assembled by chance. The whole lineup points toward a season built around cultural contrast as much as murder mystery.

For streaming availability updates and cast announcements across Disney+, Hulu, Netflix, Prime Video, and Apple TV+, we track every confirmed addition as soon as it's made official. Season 6 is shaping up to be one of the more ambitious moves in the show's five-year history, and the guest cast reveal is only the first piece of a larger puzzle.
