The mystery of Only Murders in the Building season 5 premiere date has been solved — I’m counting down the days until the new season
Plus the OMITB season 5 cast is officially confirmed.

We’re getting new episodes of Only Murders in the Building in less than two months people!
Hulu officially announced that the Only Murders in the Building season 5 premiere is arriving on Tuesday, September 9; the comedy/mystery show will stream on Disney Plus in the UK. The first three episodes of the new season are going to be available to watch right away, with single episodes releasing weekly after that.
On top of that great news, we also have the official synopsis for Only Murders in the Building season 5 and the returning and new cast members for this season. Let’s start with the synopsis:
“After their beloved doorman, Lester (Teddy Coluca), dies under suspicious circumstances, Charles (Steve Martin), Oliver (Martin Short) and Mabel (Selena Gomez) refuse to believe it was an accident. Their investigation plunges them into the shadowy corners of New York and beyond — where the trio uncovers a dangerous web of secrets connecting powerful billionaires, old-school mobsters and the mysterious residents of the Arconia. The trio discovers a deeper divide between their storied city they thought they knew and the new New York evolving around them — one where the old mob fights to hold on as newer, even more dangerous players emerge.”
In addition to the lead trio of Martin, Short and Gomez, returning cast members for this season include Michael Cyril Creighton as Howard, Meryl Streep as Loretta, Da’Vine Joy Randolph as Detective Donna Williams, Richard Kind as Vince Fish and Nathan Lane as Teddy Diams (the latter returning for the first time since season 2).
New additions to the Only Murders in the Building cast include Téa Leoni (though she did have a brief appearance in the season 4 finale), Bobby Cannavale, Renée Zellweger, Logan Lerman, Christoph Waltz, Keegan-Michael Key, Beanie Feldstein, Dianne Wiest and Jermaine Fowler.
The only thing we’re missing is a trailer for the new season, but hopefully that will arrive soon.
The latest updates, reviews and unmissable series to watch and more!
Only Murders in the Building is one of my favorite TV shows right now, so I’m beyond ecstatic to finally know when the series is coming back, even if I have to wait about a week longer than usual (most previous seasons premiered the last week of August, while season 5 arrives the second week of September). With the introduction of the mafia and a cast of A-list guest stars, which may be the show’s biggest group yet, this makes Only Murders in the Building season 5 a must-watch in my books.
