Full Cast of Only Murders in the Building Season 3 - Every Actor & Character In New Episodes

Only Murders in the Building Season 3's cast features franchise newcomers and returning actors from previous seasons.

The hit Hulu series revolves around three strangers who love true crime podcasts that eventually team up to investigate a death in their apartment building. 

While Only Murders in the Building showcased surprising guest stars, such as Sting and Amy Schumer in its first two seasons, Season 3 is expected to highlight more actors while keeping the spotlight on its star-studded cast. 

Every Actor in Only Murders in the Building Season 3

Veteran actor Steve Martin returns in Only Murders in the Building Season 3 as Charles-Haden Savage, a former TV star from the hit 90s crime drama Brazzos and a good neighbor and resident of Arconia. 

After surviving his ex who turned out to be a murderer in Season 1, and rekindling his bond with his daughter in Season 2, Steve Martin's Charles-Haden Savage is expected to have a fresh start in Season 3 with a new romantic relationship and a potential career in theatre.

Martin is best known for his roles in Cheaper by the Dozen, Father of the Bride, and Pink Panther.

Selena Gomez plays Mabel Mora, a young artist whose expertise is to rely on hard facts to solve murders alongside Putnam and Savage.

Gomez is an accomplished singer whose acting credits include Wizards of Waverly Place, Spring Breakers, and The Dead Don't Die.

Michael Cyril Creighton - Howard Morris

Michael Cyril Creighton plays Howard Morris in Only Murders in the Building Season 3, a resident from Arconia who loves cats and Oliver's assistant in the Broadway play.
