Only Murders in the Building returned for its fifth season on September 9, 2025, on Hulu, bringing back the beloved true-crime podcasting trio for a case that hits closer to home than ever before. Following the shocking discovery at the end of Season 4, the residents of the Arconia find themselves entangled in a web of billionaires, mobsters, and long-held secrets. The production, which filmed between March and June 2025, features one of the most prestigious ensembles in the history of the series.

The Iconic Core Trio Returns

The heart of the series remains the chemistry between its three lead stars, who serve as both the protagonists and executive producers of the show.

Steve Martin as Charles-Haden Savage

Charles-Haden Savage, the semi-retired actor known for his 1990s detective series Brazzos, continues to provide the moral and often overly cautious compass of the group. In Season 5, Charles's connection to the Arconia's history is put to the test. The investigation into the death of Lester, the doorman, forces Charles to reflect on his early days in the building. His character arc this season explores the vulnerability of aging within a changing New York City, especially as he faces off against the technological advancements represented by the Arconia's new robotic staff.

Martin Short as Oliver Putnam

Oliver Putnam remains the flamboyant, dip-loving theater director whose theatrical flair drives the podcast's narrative energy. In Season 5, Oliver’s storyline is heavily influenced by his recent marriage and his childhood memories of Brooklyn and Staten Island. His investigation into the Caccimelio family leads him to revisit his own past, providing a blend of high-energy comedy and genuine emotional depth. Oliver’s interactions with the season's high-profile guest stars, particularly the billionaires, highlight his desperate need for social validation and his innate talent for finding the "show" in every murder.

Selena Gomez as Mabel Mora

Mabel Mora, the youngest member of the trio, continues her transition from a drifter to a focused professional investigator. This season, Mabel’s personal life takes center stage as she reunites with an old friend, Althea, who has since become a pop superstar. This dynamic allows the series to explore Mabel’s past before she arrived at the Arconia, showcasing a more vulnerable side of her character. Selena Gomez portrays Mabel with a dry wit that balances the eccentricities of Martin and Short, serving as the audience's grounded perspective amidst the chaotic world of New York's elite.

The High-Profile New Additions

Season 5 is notable for its influx of Academy Award winners and established screen veterans, expanding the world of the Arconia to include the city's most powerful figures.

Renée Zellweger as Camila White

Academy Award winner Renée Zellweger joins the cast as Camila White, a formidable pharmaceutical heiress and hotelier. Camila is introduced as part of a trio of billionaires who become primary suspects early in the season. Zellweger brings a sharp, intimidating elegance to the role, presenting a character who is as charming as she is potentially dangerous. Her character represents the "New New York," a force that threatens the traditional charm of buildings like the Arconia.

Christoph Waltz as Sebastian "Bash" Steed

Christoph Waltz portrays Sebastian "Bash" Steed, a tech mogul with a clinical and often unsettling approach to life and business. Waltz, known for his ability to play sophisticated villains, brings a unique tension to the series. As a suspect in the murders of both Lester and Nicky Caccimelio, Bash Steed represents the cold, calculated side of modern wealth. His interactions with Charles and Oliver provide some of the season's most compelling dialogue, as two different eras of New York culture clash.

Téa Leoni and Bobby Cannavale as the Caccimelios

The introduction of the Caccimelio family brings a classic mob element to the mystery. Téa Leoni stars as Sofia Caccimelio, the wife of mobster Nicky Caccimelio, played by Bobby Cannavale. Sofia is a pivotal character who initially approaches the trio to find her missing husband, only for the investigation to reveal much darker ties to the Arconia's dry cleaning business. Bobby Cannavale’s Nicky is a presence felt throughout the season, even as the mystery of his death unfolds alongside Lester's.

Logan Lerman as Jay Pflug

Logan Lerman joins the ensemble as Jay Pflug, a billionaire heir whose missing finger becomes a central clue in the season's fourth episode, "Dirty Birds." Pflug’s character adds a layer of youthful arrogance and hidden insecurity to the suspect pool. His scenes with Mabel Mora highlight the divide between those who inherited their wealth and those who are struggling to find their place in the city.

Returning Favorites and Special Guest Stars

While new faces dominate the headlines, Season 5 maintains its continuity with the return of several key figures from previous seasons.

Meryl Streep as Loretta Durkin

The legendary Meryl Streep returns as Loretta Durkin, Oliver’s love interest and a successful actress. After her career took off in Season 3 and 4, Loretta's presence in Season 5 provides an emotional anchor for Oliver. Her involvement in the episode "Flatbush" takes the trio back to Oliver's childhood roots, deepening the romantic and narrative stakes for the season's climax.

Da'Vine Joy Randolph as Detective Donna Williams

Detective Donna Williams remains the trio's reluctant ally within the NYPD. As the police initially rule Lester’s death an accident, Detective Williams must navigate the bureaucracy of a corrupt police force while secretly aiding Charles, Oliver, and Mabel. Her no-nonsense attitude continues to provide a sharp contrast to the trio's amateur (yet effective) investigative methods.

Nathan Lane as Teddy Dimas

In a surprising return, Nathan Lane reprises his role as Teddy Dimas. Teddy’s history of illegal activities within the Arconia makes him a natural fit for a season focused on hidden casino rooms and mob connections. His appearance adds a layer of history and tension, as the trio must decide whether to trust a man who has previously tried to ruin them.

Michael Cyril Creighton as Howard Morris

Now a series regular, Howard Morris is more involved in the investigation than ever. Howard’s role as the building's gossip and occasional assistant to the trio provides much of the season's observational humor. His knowledge of the Arconia's staff and residents proves invaluable as the trio investigates the inner workings of the building's maintenance and security.

The Arconia Staff and the Victim

The central mystery of Season 5 revolves around the death of Lester, the Arconia's long-time doorman, making the building's staff a primary focus of the narrative.

Teddy Coluca as Lester

Teddy Coluca delivers a poignant performance as Lester. Although his character meets an untimely end in the fountain of the Arconia, he appears in flashbacks throughout the season, particularly in the episode "After You." These flashbacks reveal Lester’s 1993 beginnings at the building and his complicated relationship with the mob and the residents he served for decades. His death serves as the emotional catalyst for the entire season.

Jermaine Fowler as Randall Winston

With the loss of Lester, the Arconia hires a new doorman, Randall Winston, played by Jermaine Fowler. Randall’s introduction brings a fresh perspective to the building's dynamics. As a newcomer, he is often bewildered by the trio's antics, but his access to the building's ledgers and secret passages makes him an accidental key player in the investigation.

The Voice of L.E.S.T.R.

A unique addition to the "cast" is the Logic Engineered Secure Tenant Robot, or L.E.S.T.R., voiced in a cameo capacity. The robot represents the modernization of the Arconia that many residents, including the trio, find intrusive. The conflict between the human staff and the robotic replacement serves as a recurring theme throughout the ten episodes.

Recurring Guests and Notable Cameos

The world of Only Murders in the Building is populated by a rich array of supporting characters who bring the Arconia to life.

  • Jackie Hoffman as Uma Heller: The Arconia's resident curmudgeon returns to provide her trademark insults and cynical observations.
  • Richard Kind as Vince Fish: Following his introduction in Season 4, Vince Fish remains a part of the Arconia's eccentric community, often found at the center of building meetings that descend into chaos.
  • Beanie Feldstein as Althea: Playing Mabel’s childhood friend turned pop star, Feldstein adds a layer of "Gen Z" celebrity culture to the show's mix of old-school mystery.
  • Keegan-Michael Key as Mayor Beau Tillman: Key portrays the Mayor of New York, who becomes involved when the investigation threatens to expose corruption at the highest levels of city government.

How the Season 5 Cast Enhances the Mystery

The casting choices for Season 5 are not merely for star power; they are deeply integrated into the season's themes of "Old New York" versus "New New York." By casting veterans like Dianne Wiest (who plays Lorraine Coluca) alongside modern stars like Logan Lerman, the show visually and narratively represents the conflict between the building's storied past and its commercialized future.

The chemistry between the billionaires—Zellweger, Waltz, and White—creates a formidable wall of wealth that the trio must dismantle. Unlike previous seasons where the killer was often a lone actor or a pair, Season 5 suggests a broader conspiracy involving the city's power players, necessitating a cast that can carry that level of gravitas.
