Character Details Remain Under Wraps
As is typical for the series, the production is keeping all character details under wraps. Neither Hulu nor the creative team has revealed who any of the 20 guest stars will play, leaving fans to speculate whether the newcomers are suspects, allies, or red herrings.
Why Is Only Murders Filming in the UK for the First Time?
Production on Season 6 is currently underway in the U.K., marking the first time the series has filmed outside the United States. The shift follows directly from the Season 5 finale cliffhanger, which left leads Charles-Haden Savage (Steve Martin), Oliver Putnam (Martin Short), and Mabel Mora (Selena Gomez) confronting the death of investigative podcaster Cinda Canning.
The Season 5 Finale Cliffhanger
Cinda Canning’s death at the close of Season 5 sent the trio’s story in a new direction. Rather than continuing to investigate murders inside The Arconia on New York’s Upper West Side, the podcasting amateurs are following the mystery across the Atlantic.
What We Know About the London Setting
London will serve as the primary backdrop for the new season’s central mystery. The series is from co-creators Steve Martin and John Hoffman, with 20th Television as the studio. Executive producers include Martin, Short, Gomez, Dan Fogelman, Hoffman, Jess Rosenthal, Ben Smith, Jennifer Crittenden, and Gabrielle Allan.
David Tennant and Jodie Whittaker: Two Doctors, One Mystery
Among Season 6’s most eye-catching bookings is the pairing of Tennant and Whittaker, who both played the Doctor in Doctor Who — Tennant as the Tenth and Fourteenth Doctors, Whittaker as the first woman to take on the role. Their casting gives the London season a distinct British-TV pedigree.
Notable Credits Across the Guest Cast
The guest list reads like a who’s-who of prestige film and television. Jim Broadbent played Horace Slughorn in the Harry Potter franchise. Nicola Coughlan became a global name through Bridgerton.
Richard Ayoade is known for The IT Crowd, Anjana Vasan for Killing Eve and Wicked, and Simone Ashley for Bridgerton and Sex Education.
With characters still secret, the sheer range of talent suggests the production is casting a wide net — whether these figures are allies, suspects, or one-off cameos remains to be seen.
Will Da’Vine Joy Randolph Return for Season 6?
Da’Vine Joy Randolph, who earned widespread acclaim for her Season 4 role on the show, has been photographed on set. However, Hulu has not officially confirmed her return or disclosed any character details.
Randolph’s presence has fueled fan speculation that she could reprise her detective role in the London investigation. Until the studio confirms, her involvement remains unverified.
