Here's Every Single Thing We Know About "Only Murders In The Building" Season 3, Including Who's Joining The Cast

Meryl!!!!!! Streep!!!!!!!!!!!

Only Murders in the Building is the cutest, silliest show about gruesome murders currently on TV.

Hulu

The show is back on Hulu for its third season which has had more mystery, more comedy, and more movie stars than ever before.

Hulu

Here are all the details with as little spoilers as possible:

1. SEASON 3 IS CURRENTLY AIRING, with two episodes having dropped on Hulu on August 8. Since then, we've gotten one episode per week.

I can't tell you how much I appreciate that OMITB doesn't make us suffer for too long in between seasons.

2. The release date wasn't affected by the ongoing WGA and SAG-AFTRA strikes, but the cast hasn't done any press for Season 3.

3. Main cast members Steve Martin, Martin Short, and Selena Gomez are, of course, back for Season 3.

4. Joining them are former Sexiest Man Alive Paul Rudd and actual living legend Meryl Streep.

Paul Rudd appeared in the Season 2 finale as Ben Glenroy, Charles's co-star in a new play directed by Oliver. He only had one scene, but it was enough time to establish that he and Charles hated each other. It was also enough time for him to die onstage.

Meryl Streep's character is named Loretta Durkin, and she's also a cast member in the play.

5. The main plot of Season 3 is about how Ben Glenroy died.

Hulu

Here's the official season synopsis from Hulu: 

"Season 3 finds Charles, Oliver & Mabel investigating a murder behind the scenes of a Broadway show. Ben Glenroy is a Hollywood action star whose Broadway debut is cut short by his untimely death. Aided by co-star Loretta Durkin, our trio embarks on their toughest case yet, all while director Oliver desperately attempts to put his show back together."

There you have it! Like Tim Kono and Bunny before him, Ben is this season's victim. And, as was confirmed in the trailer, Charles, Oliver, and Mabel will once again be podcasting about it.

6. And yes, that will involve finding out what happened during the year-long time jump we saw in the Season 2 finale.

One big change right off the bat: Mabel has bangs, huge news.

8. There. Are. MUSICAL NUMBERS!!!!!

Hulu

It's unclear whether there will be a full musical episode, but there will definitely be a few songs during the season. 

9. Other returning cast members include Andrea Martin, Ryan Broussard, and Michael Cyril Creighton, who was promoted to series regular for Season 3.

Hulu

They play Charles's girlfriend Joy, Oliver's son Will, and cat-loving Arconia neighbor Howard, respectively. 

10. The trailer confirmed the return of Da'Vine Joy Randolph as Detective Williams, Jane Lynch as Sazz Pataki and Tina Fey as Cinda Canning.

Hulu

It seems like Detective Williams will have a guest role rather than a recurring role this season, so we might only see Da'Vine Joy Randolph for one episode. Tina Fey had a larger presence as Cinda in Season 2, but it also looks like it's been scaled back to guest appearances for Season 3. As for Jane Lynch's Sazz, whatever time we get with her won't be enough.

11. James Caverly as Theo Dimas is back too!

I love Theo and Mabel's dynamic, so here's to seeing more of it.

12. There's also several new recurring characters, including Ashley Park as Tik-Tok obsessed Broadway ingenue Kimber and Jesse Williams as Tobert, a documentarian with a "particular interest" in the main trio...Mabel in particular.

13. Also joining the cast are Wesley Taylor, Jeremy Shamos, Linda Emond, Don Darryl Rivera, Allison Guinn, and Gerald Caesar.

14. And also Matthew Broderick as...Matthew Broderick!!

Hulu

Matthew Broderick plays a fictionalized version of himself in what in yet another amazing guest performance on OMITB.

15. Nathan Lane is (tragically) not returning in a prominent role, but he might "pop in" at some point during the season.

I will take any amount of Teddy Dimas I can get.

16. One recurring character whose return hasn't been confirmed yet is Charles's stepdaughter Lucy, played by Zoe Colletti.

17. Cara Delevingne could return, but we shouldn't expect Alice and Mabel's romance to rekindle.

Co-creator John Hoffman confirmed that any future relationship between the two women would be strictly platonic.

18. And finally: Mabel will, at some point, wear a massive, gorgeous wedding dress and be escorted to a cab by her doting granddads.

Is this a dream sequence? Is Mabel getting married?? I have no additional context for this image, but call me a cat because the curiosity is killing me.
