Meet the Cast of Only Murders in the Building Season 5

– Steve Martin as Charles-Haden Savage

Steve Martin returns with impeccable comedic timing and unexpected depth as the once-famous actor Charles-Haden Savage. This season, Charles grapples with the legacy of his Brazzos fame while fully leaning into his role as the trio’s “method investigator.” Martin brilliantly portrays Charles’s endearing awkwardness, whether he’s attempting to recreate a crime scene with theatrical flair or navigating his evolving, almost paternal relationship with Mabel. His character’s journey is one of finding purpose beyond the spotlight, using his actor’s intuition to decode the subtlest of clues.

Martin’s chemistry with Martin Short and Selena Gomez remains the series’ undeniable core. This season, Charles is forced to confront a mystery from his own past that intertwines with the current case, adding layers of vulnerability and resolve to his character. Martin ensures that Charles is both the hilarious relic of a bygone era and the emotional anchor of the group, proving that even a faded star can be a hero.

– Martin Short as Oliver Putnam

Martin Short is a tour de force of energy and extravagance as the eternally dramatic Oliver Putnam. Short delivers every line with the flourish of a Broadway soliloquy, turning even the most mundane clue into a life-or-death spectacle. This season, Oliver’s theatrical direction of the investigation reaches new heights—sometimes to the trio’s benefit, often to their peril. His unwavering passion for storytelling (and gourmet dips) continues to drive the podcast’s success, even as the stakes become dangerously real.

Short’s performance is a masterclass in physical comedy and heartfelt expression. Beyond the humor, Oliver’s deep loyalty to Charles and Mabel shines through, especially when the case threatens to tear them apart. Short brings a touching vulnerability to Oliver’s larger-than-life persona, reminding us that beneath the designer scarves and melodrama beats the heart of a true friend.

– Selena Gomez as Mabel Mora

Selena Gomez grounds the series with her sharp, soulful performance as Mabel Mora, the trio’s resident Gen Z detective and artistic genius. Gomez portrays Mabel’s growth from a lost soul into a confident investigator with nuance and strength. This season, Mabel’s skills are put to the ultimate test as the murder investigation forces her to question everyone in the building—including those she’s grown to trust. Her cool demeanor and quick wit are her greatest assets, but even she can’t stay detached when the mystery hits close to home.

Gomez’s deadpan delivery provides the perfect counterbalance to Martin and Short’s antics, creating a dynamic that is both hilarious and heartwarming. Mabel’s journey this season is one of self-discovery, as she balances her sleuthing ambitions with the desire for a normal life. Gomez ensures that Mabel remains the relatable, resilient heart of the operation.

– Michael Cyril Creighton as Howard Morris

Michael Cyril Creighton steals scenes as the cat-obsessed, endlessly gossipy Howard Morris. This season, Howard’s knowledge of the Arconia’s residents proves more valuable than ever, as he serves as the trio’s unofficial archivist and informant. Creighton brings a delightful blend of nervous energy and unwavering loyalty to the role, making Howard both a hilarious sidekick and an unlikely hero.

Creighton’s performance adds layers of community and charm to the narrative. Howard’s evolving friendship with the core trio, especially his shared moments with Oliver, provides some of the season’s most endearing and comedic moments. He is the embodiment of the building’s quirky soul.

– Jackie Hoffman as Uma Heller

Jackie Hoffman delivers her signature acerbic wit as Uma Heller, the Arconia’s most brutally honest and pessimistic resident. Hoffman’s impeccable timing and no-nonsense demeanor make Uma a fan favorite, whether she’s critiquing Oliver’s fashion choices or dropping a crucial piece of information disguised as an insult. This season, Uma’s cryptic knowledge of the building’s history becomes a key asset—if the trio can decode her grumpy commentary.

Hoffman’s portrayal is a masterclass in comedic cynicism. Uma’s reluctant involvement in the investigation adds a layer of gritty realism to the otherwise whimsical world of the show. She is the voice of sarcastic reason in a building full of chaos.

– Teddy Coluca as Lester

Teddy Coluca returns as Lester, the Arconia’s long-suffering but eternally polite doorman. Coluca brings a gentle, watchful presence to the role, portraying Lester as the quiet observer who sees everything but says very little. This season, Lester’s detailed memory of comings and goings becomes instrumental in piecing together the timeline of the murder.

Coluca’s performance is understated yet impactful. Lester’s loyalty to the residents, particularly the trio, adds a sense of warmth and stability to the narrative. He is the calming force at the front door of a building constantly swirling with mystery.

– Da’Vine Joy Randolph as Detective Donna Williams

Da’Vine Joy Randolph reprises her role as Detective Donna Williams, the no-nonsense NYPD detective who is equal parts annoyed and impressed by the trio’s sleuthing skills. Randolph brings a commanding presence and sharp humor to the role, portraying a professional who is tired of finding Charles, Oliver, and Mabel at every crime scene but can’t deny their results.

Randolph’s chemistry with the trio is brilliantly tense and funny. Detective Williams serves as the official foil to their amateur investigations, and her gradual, grudging respect for their methods adds a satisfying dynamic to the show. She is the law breathing down their necks, and Randolph makes every interaction a highlight.

– Russell G. Jones as Dr. Grover Stanley

Russell G. Jones joins the cast as Dr. Grover Stanley, a mysterious new resident with a professional expertise that makes him both a valuable ally and a potential suspect. Jones brings an air of intellectual authority and enigmatic charm to the role, keeping the trio—and the audience—guessing about his true intentions.

Jones’s performance adds a new layer of intrigue to the season. Dr. Stanley’s conversations with the trio are filled with psychological insight and subtle tension, making him a wildcard in the investigation. He represents the new blood in the Arconia, whose secrets are as deep as those of the long-term residents.
