Only Murders in the Building Season 3: Everything We Know So Far

Only Murders in the Building wrapped up Season 2 this summer with another bloody installment, leaving fans dying for a third season. The finale, "I Know Who Did It," set up a whole new mystery for our trio to solve; after butting heads with Charles (Steve Martin) backstage at Oliver's (Martin Short) latest production, Broadway star Ben Glenroy (Paul Rudd) seemingly dropped dead mid-monologue, much to the horror of the full house.

"You've gotta be f*cking kidding me," Mabel Mora (Selena Gomez) huffed, as frantic onlookers surrounded Glenroy's body. So who killed Ben Glenroy? The crime-solving trio is bound to be back on the case. 

Hulu has renewed the Emmy Award-nominated series for Season 3, and casting for the next installment is already underway. Here's everything we know about Only Murders in the Building Season 3 so far.

What is Only Murders in the Building Season 3 about? 

Hulu has not revealed an official synopsis for the third season, but based on the Season 2 finale, it will likely revolve around the murder of Ben Glenroy, which takes place a year after the events of Season 2. After the conflict between Ben and Charles in the finale, it seems as though we have a lot to learn about what connection Ben has to our central trio — and who could possibly want him dead. 

"I’m about six weeks into writing with the room for Season 3, and what we have planned is insane and so exciting. It’s also very twisty," co-creator John Hoffman told TV Line in August. "We try to check ourselves, like, 'OK, what can we do and how can we do this differently?' and 'What feels like a different take? A fresh take?' So I can only say hang tight! There’s a lot going on, and certainly the victim is colorfully drawn so far."

"If Season 1 was a little more focused on the emotional storyline for Mabel and Tim Kono, and Season 2 was a little more emotionally connected to Charles and his relationship with his father and himself, I’m very excited to both lean into the theatrical side of New York City and also into Oliver and his world," he explained to The Hollywood Reporter. 

When will Only Murders in the Building Season 3 Premiere? 

While a premiere date for Only Murders in the Building Season 3 has not been announced just yet, there's a big chance the next installment will debut in 2023 (based on the release schedule so far). 

Who is in the cast of Only Murders in the Building Season 3?

Martin, Short, and Gomez have all been confirmed as returning for Season 3 in their respective roles. Paul Rudd was officially announced as a new cast member for the third season following his surprise appearance as the show's latest victim in the Season 2 finale. 

Grey's Anatomy star Jesse Williams has also joined the cast in a recurring role, playing a documentarian interested in our trio's latest case. Other returning cast members have not been announced yet, but it's likely we'll see Arconia residents and supporting players like Jackie Hoffman, Michael Cyril Creighton, Da'Vine Joy Randolph, Nathan Lane, James Caverly, and Jason Veasey back for another season. 

Amy Schumer, Jane Lynch, Tina Fey, Michael Rappaport, Shirley MacLaine, Sting, Andrea Martin, and Mark Consuelos have all made guest appearances on the show. But Season 3 might have landed the biggest star yet: Meryl Streep has just been cast in an as-yet-unknown role. Martin (as in Steve) posted the news to his Twitter account on January 17:
