Only Murders In The Building Season 6 Roster Swells To 14 Guest Stars, Including Martin Freeman, Sharon Horgan, And Simone Ashley

With the Arconia's future secured, Charles, Oliver and Mabel are heading across the pond for their next investigation.

Hulu renewed "Only Murders in the Building" for Season 6 on October 28, mere hours after the Season 5 finale dropped. The streamer also confirmed at the time that the long-running whodunit would film Season 6 in London.

"Only Murders in the Building" Season 5 ended with the surprise return of Tina Fey's Cinda Canning, who hadn't been seen since Season 3.

In the finale's closing minutes, Charles, Oliver, and Mabel tuned into Cinda's new true-crime podcast, "The Girl With the Curls," which followed a young woman accused of murder in London. Moments later, that same red-haired woman fell to her death outside the Arconia — though she technically died in the building after grabbing the gate with her final breath. 

The victim's face was then revealed: It was Cinda herself.

When Hulu renewed "Only Murders in the Building" for Season 6, the streamer revealed that Charles, Oliver, and Mabel would leave New York behind to investigate a new mystery in London. At the time, however, it did not specify which cast members would be joining Steve Martin, Martin Short, and Selena Gomez for the trip abroad.

Since then, Hulu has confirmed that recurring guest star Da'Vine Joy Randolph will return as Detective Donna Williams. And given the Season 5 finale's game-changing reveal, it also seems likely that Tina Fey's Cinda Canning will play a major role in the next chapter.

As of June 11, TVLine has confirmed the following 14 guest stars will appear in "Only Murders in the Building" Season 6:

1. Simone Ashley ("Bridgerton")
2. Matthew Beard ("Magpie Murders")
3. Amar Chadha-Patel ("Willow")
4. Jamie Demetriou ("Stath Lets Flats")
5. Martin Freeman ("Sherlock")
6. Geri Halliwell-Horner (the Spice Girls)
7. Sharon Horgan ("Bad Sisters")
8. Jane Horrocks ("Absolutely Fabulous")
9. Derek Jacobi ("Vicious")
10. Lesley Nicol ("Downton Abbey")
11. Rhea Norwood ("Heartstopper")
12. Jennifer Saunders ("Absolutely Fabulous")
13. Sean Teale ("Doctor Odyssey")
14. Anjana Vasan ("We Are Lady Parts")

Character details are being kept under wraps.
