Mabel Mora is a tough and street-smart artist who harbors many secrets. She’s obviously pretty different from her fellow residents in the Arconia, as she does not have the means to be one, staying there temporarily to renovate her aunt’s apartment.

Mabel is played by Selena Gomez, who is best known for her role in Disney’s Wizards of Waverly Place. However, since then, she’s made a major name for herself as a popstar and actor.

Oliver Putnam: Martin Short

Oliver is arguably the biggest comic relief out of the main trio, though this season will be giving him more drama. Like Charles, Oliver is also flailing in the entertainment industry, though the latter is arguably doing worse, as he is pretty much broke. Oliver loves to be in the spotlight, hence why he takes the lead in the podcast.

Martin Short plays Oliver, and is also well know for starring in Father of the Bride, Treasure Planet, and The Santa Clause 3.

Ben Glenroy: Paul Rudd

Paul Rudd in Only Murders in the Building, who'll return in the Season 3 castDisney+

Ben Glenroy is the victim of this season, having died onstage at the end of Season 2. It’s clear that he and Charles have had some issues with each other, which will no doubt play into Ben’s character as we find out more about him.

This murdered soul is played by Paul Rudd, otherwise known for his starring role in the MCU’s Ant Man, along with comedies Clueless and Friends.

Loretta Durkin: Meryl Streep

Like Ben, Loretta is a new character, involved in Charles and Oliver’s new play. Loretta seems to struggle with acting somewhat, especially at table reads, but she becomes very close with Oliver.

Meryl Streep plays Loretta, which brings a sense of irony to the character, as Streep is one of the greatest actors out there. She’s won Oscars left and right for Sophie’s Choice, The Iron Lady, and what should have been The Devil Wears Prada.

Tobert: Jesse Williams

Tobert is another new character, and is a documentary producer who takes an interest in the murder case of Ben Glenroy. He also takes an interest in Mabel, and seems to be the new love interest for her this season.

Howard from only murders in the buildingDisney+

Howard Morris is one of the many tenants at the Arconia. He’s a shy yet simultaneously gossipy man, who works at the Public Library, and is later Oliver’s assistant for his Broadway show. He also has pretty bad luck with both pets and dating.

Jonathan: Jason Veasey


Jonathan is Ben’s understudy in Oliver’s musical, and Howards boyfriend that also lives in the Arconia. He is exceptionally talented, hosting a variety of Broadway jobs, and singing at high-end restaurants. We first met Jonathan in Season 2, where it was revealed that he is greatly allergic to cats.

Will is Oliver’s son, who does his best to deal with his father’s rather audacious ambitions, despite having a family of his own to deal with. He appears far more straight-laced than his father, but does take an interest in musical theatre when it comes to the school he works at.

Donna and Clifford Demeo are the producer of Oliver’s newest play, Death Rattle. They work well as producers, but have somewhat of an odd, borderline Freudian relationship. However, despite being a mama’s boy, Clifford has some pretty good connections of his own in the industry.
