Only Murders in the Building Season 6: New Cast Additions and What to Expect

The hit Hulu mystery comedy Only Murders in the Building is heading across the Atlantic for its sixth season, and the cast is growing with some major star power. The upcoming season is currently filming in London, a first for the series that has previously been set entirely in New York City. Season 6 is expected to debut on Hulu and Disney+ internationally in Fall 2026.

The season will continue to follow the crime-solving trio of Charles, played by Steve Martin; Oliver, played by Martin Short; and Mabel, played by Selena Gomez. They will travel to the UK to continue their investigation into the death of Cinda Canning, the rival podcast host played by Tina Fey, who was last seen meeting a suspicious end in the Season 5 finale.

Star-Studded New Cast Announcements

Production has officially started, and a long list of acclaimed actors have been confirmed as recurring guest stars for Season 6. The casting news, which broke in mid-June 2026, reveals a mix of British and Irish talent joining the series.

The new additions include a trio of actors known for their time in the TARDIS: David Tennant and Jodie Whittaker will join alongside Nicola Coughlan of Bridgerton and Derry Girls fame, the legendary Jim Broadbent, and comedic actor Richard Ayoade. A complete list of the newly announced cast members includes David Tennant, Nicola Coughlan, Jodie Whittaker, Jim Broadbent, Richard Ayoade, Adrian Lukis, and Kathryn Hunter.

These actors join a previously announced list of guest stars that includes Martin Freeman, Spice Girl Geri Halliwell-Horner, Jennifer Saunders, Sharon Horgan, Jamie Demetriou, Derek Jacobi, and Simone Ashley. As with previous seasons, exact character details for the new cast members are being kept under wraps.

Return of Familiar Faces

While the main trio is confirmed to return, the status of other familiar faces is still unclear. Michael Cyril Creighton, who plays Howard, is set to return. Da’Vine Joy Randolph, who won an Oscar and appeared in Season 5, has been spotted on set, but her official return has yet to be confirmed by the studio. The show has a history of bringing back fan-favorite guest stars, so audiences can likely expect more surprises as the season unfolds.
