When it comes to the biggest shows on streaming platforms right now, one that always comes to mind is Only Murders in the Building. The series, starring Steve Martin, Martin Short, and Selena Gomez, has been running since 2021 and follows the story of three residents of an apartment building who end up getting themselves tangled in a murder investigation for their new true crime podcast, “Only Murders in the Building.”

The show’s second season came to an end in August 2022, and with that Season 2 ending cliffhanger, I’m sure you, like many others, are wondering when the heck Season 3 is going to come around to answer all those questions. While there isn’t that much information plot-wise about what to expect, we do know at least a little bit of what Season 3 has to hold. Let’s get into it.  

What Is The Only Murders In The Building Season 3 Premiere Date?

Thankfully, we can confirm that Only Murders in the Building Season 3 is set to release August 8th, 2023.  It was confirmed at Steve Martin’s tour, “You Won’t Believe What They Look Like Today!” at the Walt Disney Theater (via Variety). 

This is super great news, and a great addition to our 2023 TV premiere schedule. I am so excited to see what comes next for them and for August to get here as soon as possible.  

Selena Gomez, Martin Short, And Steve Martin Are Expected To Be Back For Season 3

Recently,  it was confirmed that Selena Gomez, Martin Short, and Steve Martin are all set to return in Season 3 of the series. 

At first, we didn’t get much confirmation that they were going to be back besides the obvious cliffhanger at the end of Season 2, but when filming started, it was confirmed that everyone was there in a video that Selena Gomez posted to her Instagram featuring her and the rest of the cast – along with a few surprise guest additions, but we’ll get into that down below. 

Paul Rudd, Meryl Streep, And More Have Joined The Cast

While we already have a pretty star-studded cast in Only Murders in the Building, with comedic legends like Steve Martin and Martin Short, and the iconic actress and singer, Selena Gomez, another person has signed on for Season 3 - and that is the amazing Paul Rudd.

Confirmed by Deadline, it was announced that Rudd would officially be joining the main cast in Season 3 of Only Murders in the Building, after his surprise guest appearance in the Season 2 finale. He will continue to play Ben Glenroy, the actor who stars in the play that Oliver Putnam is directing, and falls dead on the stage just as that show began in the finale. 

Meryl Streep

Having Paul Rudd join the cast is fun, but you know who else is joining this cast? A queen herself, Meryl Streep. 

In a surprising piece of news that came out in January 2023, it was confirmed that famed movie mega-star, Meryl Streep, was actually confirmed to be joining the cast. In a video that was posted to Selena Gomez’s Instagram account, the one that we brought up above,t, the actress showed a video of her as well as her co-stars, new addition Paul Rudd, returning cast member Andrea Martin, and then at the very end, Meryl Streep appeared. 

That same day, it was also confirmed by Deadline that Meryl Streep has officially joined the cast of Only Murders in the Building Season 3. While details of who she is going to play have remained sealed, it’s still an exciting piece of news to see her in another television show!

The last time Streep was on the main cast for a television show was on the popular HBO Max series, Big Little Lies during Season 2, for which she was nominated for a Primetime Emmy award for her performance, so it’s so great to see her come back to television for this series – alongside another 2023 television role in the upcoming series, Extrapolations, according to Deadline. Also confirmed to return in Season 2 is Andrea Martin, as we saw in the Instagram video above, where she’ll be returning as Joy, the makeup artist and love interest of Charles, as we weren’t sure if she would be back from Season 2. 

Other cast members for Season 3

Some more casting news we can confirm is that Ashley Park has also joined the cast as Kimber, a performer on Broadway, according to Deadline. Also confirmed is Jesse Williams joining on as a documentarian in a recurring role.

Several other stars have been added on as recurring characters as well, including Jeremy Shamos, Linda Edmon and Wesley Taylor. Other roles that were confirmed in a recurring matter are Don Darryl Rivera, Allison Guinn and Gerald Caesar, whose parts are being kept under wraps for now. 

Some other new casting news is also that Michael Cyril Ceighton, who plays Howard Morris (you know, the lover of cats and gossip) has been upgraded to a series regular role, according to Deadline, so we’ll be seeing a lot more of him soon enough!  

Season 3 Is Going To Answer The Biggest Question Of The Season 2 Finale - What’s Going On Between Charles And Ben?

Literally, the biggest question any of us have for Season 3 of Only Murders in the Building is what the heck happened between Charles and Ben before that opening performance for Charles to deal that vague threat to Ben? It clearly wasn’t anything good. 

And, Hoffman, in his interview with Deadline regarding Paul Rudd’s addition to the series, was quick to say that Season 3 is going to dive right into that inquiry head on: 

The tease there that is teed up between Charles and Ben is what we’re going to reveal in Season 3. There is very sort of pointed things that Charles is saying to Ben. It’s clear that there’s huge tension between these two actors for their Broadway opening and the source of that will be revealed in Season 3. There are things being said by Charles like, ‘I know what you did,’ and ‘Stay away from her.’ All of that is a tee-up to where we’re going next season. If there’s one thing to hold onto here is ‘her identity.'

I’m dying to know who ‘her’ is and it kills me that I’m going to need to wait to find out, but patience is a virtue and I can be calm - even if I’m going to hate every second of it.

Mabel And Alice Won’t Be Together In Season 3

A big plot point of Season 2 of Only Murders in the Building was Mabel’s relationship with Alice (played by Cara Delevingne), an artist who had her share of secrets, and someone who ended up using Mabel’s trauma for her own art. But, eventually the two came to a truce after Alice apologized. 

Their relationship at the end of Season 2 was left a little open-ended, as we see Mabel in the one-year time jump at the theater to support Oliver’s play, but not Alice. One might wonder if that meant that these two were going to end up being together again, but series co-creator, John Hoffman, was quick to deny that in an exclusive interview with TVLine:

Alice’s storyline (resolved itself) in a rather sweet way, with the beginning of a reparation in that friendship (with Mabel). I like the chumminess that’s there. But I don’t think we’re aiming towards any more of a love relationship.

There’s that answer. No romance for these two. However, it would be nice to see their friendship dynamic again, because I did enjoy seeing these two real-life best friends act on screen together. Their chemistry was great. 

We Won’t Be Meeting Emma, But We Will Be Seeing Lucy More

Another character that we got to meet in Season 2 of Only Murders in the Building was Lucy, Charles’ sorta-stepdaughter-ish, where we got to see how much she has grown since Charles once took care of her before Emma (Lucy’s mother) left him ages ago. And, while Charles seems to be growing closer to Lucy, fans might wonder if Emma will make an appearance. 

However, Hoffman again shut that theory down in the same interview from TVLine, saying that it’s clear Charles has moved on, so we probably won’t be seeing Emma anytime soon:

Charles is so focused on Lucy, and he’s come to terms with (Emma moving on), so no. I think the relationship with Lucy is really sweet and has progressed nicely in Season 2, so that’s the one we’ll keep on track with (moving forward).

Lucy was a great addition to the show and a fun character to include with the main trio on some of their adventures, so it’ll be fun to see where she’s taken in Season 3, considering she is seen in the theater alongside Mabel in the one-year time jump.
