Introduction to the Only Murders in the Building Season 2 Cast
The core trio remains central to the second season of Only Murders in the Building, while a richer supporting ensemble deepens the mystery and emotional stakes. This profile focuses on the main cast—Oliver, Mabel, and Charles—alongside key recurring characters introduced or expanded in season two. Each actor brings specific comedic and dramatic textures that shape the season’s tone. Below, we break down primary and secondary performers, their character functions, and how their dynamics shift across the season.
Main Cast Profiles
Steve Zissis as Oliver Putnam
Oliver is a once-famous actor clinging to relevance, running a podcast about true crime with Mabel and Charles. Zissis balances Oliver’s vanity and insecurity, grounding the character in relatable desperation and flashes of sincerity. His performance adds a layer of faded Hollywood glamour that contrasts with Mabel’s earnestness and Charles’s anxiety, making their collaborative investigations feel uneven yet complementary.
Selena Gomez as Mabel Mora
Mabel is the meticulous, kind-hearted fan who moves in with Charles and Oliver. Gomez portrays Mabel with a mix of naivete and sharp intuition, driving much of the season’s emotional undercurrent. Her dedication to solving the mystery stems from loyalty and a desire to belong, and Gomez’s portrayal avoids caricature by conveying vulnerability alongside competence.
Martin Short as Charles-Haden Savage
Charles is a former actor desperate to relive past glory, and Short leans into the character’s performative anxiety and desperate charm. His chemistry with Gomez and Zissis anchors the trio, and Short’s timing enhances the season’s humor while lending pathos to Charles’s insecurities. The evolution of Charles’s self-awareness becomes a key arc in season two.
