Those who love true crime and being faced with a decent mystery to solve should check out Only Murders in the Building, the Hulu series that is making waves and deserves attention. Created by Steve Martin and John Hoffman, this 2021 production follows Charles-Haden Savage, Oliver Putnam, and Mabel Mora, three residents of The Arconia, a luxury building on the Upper West Side. They do not initially know each other, but share the same obsession: a true-crime podcast hosted by Cinda Canning. When one of the building's neighbors dies under strange and mysterious circumstances, these die-hard crime fans decide to join forces, create a podcast of their own, and ultimately solve the mystery.

Only Murders in the Building currently boasts two hit seasons, and was renewed for a third this past July. The show has been acclaimed by critics and audiences alike, mainly for its leads' performances, whose chemistry goes beyond the screen. Moreover, it is not a typical crime series; instead, it has a comedic and light-hearted twist, allowing viewers to enjoy the story and have fun while trying to solve each mystery alongside the main characters. Martin Short, Steve Martin and Selena Gomez do a wonderful job playing these characters that are so different from each other, yet perfectly complement one another.

They also serve as executive producers and are joined by an ensemble cast of talented actors with wide-ranging careers in film, television, and on stage, such as Amy Ryan, Tina Fey, Nathan Lane and Michael Cyril Creighton, to name a few. The third season of the series will feature Paul Rudd playing a new character challenging the leads: he will be involved in their first murder case beyond The Arconia. Here are some unknown facts about the cast of Only Murders in the Building.

Given such an important cast, it was to be expected that shooting on-location, particularly in New York City, would be a challenging task. Yet, Gomez's shots were nearly impossible to pull off due to her popularity. In an interview with Town and Country Magazine, Aaron Dominguez, who plays Oscar Torres, commented that, while filming on-location, they were surrounded by paparazzi and Gomez's fans cheering her name as much as they could, making it very difficult to stay in character.
