In the show's Hollywood-focused Season 4 trailer, we learn that Charles (Steve Martin), Oliver (Martin Short), and Mabel's (Selena Gomez) podcast is getting a film adaptation. And who's going to play our lovable heroes? None other than Eugene Levy, Zach Galifianakis, and Eva Longoria.

But movie stardom isn't the only thing on the Only Murders' crew's minds. They're also hot on the case of who killed Charles' stunt double Sazz (Jane Lynch) back in Season 3. And from the looks of the trailer, Levy, Galifianakis, and Longoria are ready to join in on the investigation.

Only Murders in the Building Season 4 also stars Michael Cyril Creighton, Richard Kind, Melissa McCarthy, Kumail Nanjiani, Da'Vine Joy Randolph, and Molly Shannon.

Only Murders in the Building Season 4 premieres Aug. 27 on Hulu.
