Only Murders In The Building Season 5 Returns With Star-Studded Cast, New Mysteries

Only Murders in the Building returns for its fifth season on Hulu with a three-episode premiere that dives into a new murder mystery centered on the death of Lester Coluca, the Arconia's doorman. The trio of amateur sleuths—Charles (Steve Martin), Oliver (Martin Short), and Mabel (Selena Gomez)—investigate connections to the mob, leading them to uncover a secret casino beneath the building and the involvement of mobster Nicky Caccimelio, played by Bobby Cannavale. Season 5 features an impressive roster of guest stars including Oscar winners Christoph Waltz as tech billionaire Sebastian "Bash" Steed, and Renée Zellweger as billionaire Camila White, alongside returning characters and familiar faces from previous seasons. The narrative explores the Arconia's history, Charles provides context on its transformation from stable to casino, and the trio conducts forensic analyses to piece together the timeline of Nicky's and Lester's deaths. With a mix of humor, suspense, and nostalgia, the season continues to blend mystery and comedy, enriched by the strong chemistry of the main cast and a star-studded supporting lineup.
