Only Murders in the Building Season 5: New Cast Members and Production Updates
Hulu has officially confirmed that Only Murders in the Building will return for a fifth season, with production currently underway in New York City. The hit mystery-comedy series, which follows the amateur sleuthing trio of Charles-Haden Savage, Oliver Putnam, and Mabel Mora, is expanding its ensemble cast as the show shifts its focus toward a new investigation following the Season 4 finale.
Who are the new cast members joining Season 5?
The upcoming season features a mix of returning leads and notable new additions to the Arconia’s orbit. According to Variety, the series has added Tia Leoni and Téa Leoni to the roster. Furthermore, Deadline reports that Jin Ha has joined the cast in a recurring role. These actors join series regulars Steve Martin, Martin Short, and Selena Gomez, who continue to anchor the show as the central investigative team.
The casting strategy for the show has consistently relied on a blend of industry veterans and high-profile guest stars. By integrating new characters like those played by Leoni and Ha, the production maintains the series’ precedent of introducing fresh suspects and allies to keep the central mystery dynamic.
What is the plot focus for the new season?
Season 5 will pick up immediately following the conclusion of the fourth season, which saw the trio solving the murder of Sazz Pataki. As reported by The Hollywood Reporter, the new episodes are expected to revolve around the mystery of the Arconia’s building manager, Lester, whose story arc became a focal point in the final moments of the previous season. Showrunner John Hoffman has indicated in press statements that the upcoming narrative will explore the deeper history of the apartment complex itself.
