Only Murders In The Building Season 4: Which Cast Members Are Returning, And Who Are The New Stars?

If you happen to be a character living at the Arconia or even stepping foot in the affluent apartment building, God help you, because there’s a not-insignificant chance you could be murdered within its premises. But one character’s untimely demise each season makes for captivating TV in real life, as Only Murders in the Building has cemented itself as one of the best Hulu TV shows. Only Murders Season 4 is now in the works, with the mystery this time around focused on who gunned down Jane Lynch’s Sazz Pataki, who recurred in the first three seasons.

Hulu subscribers can look forward to Season 4 premiering on the 2024 TV schedule on August 27, with this new batch of episodes seeing the starring characters going to Los Angeles when a Hollywood studio wants to make a movie about their podcast. More importantly in this case, we do know who will be making up the cast for this next batch of episodes. So let’s go over which Only Murders in the Building cast members are returning for Season 4, and which new stars will be accompanying them.

Which Stars Are Returning From Past Seasons?

Steve Martin

As with the following two entries on this list, it’d be weird if Steve Martin didn’t return for Only Murders in the Building Season 4 considering he plays one of the main characters. That said, it’ll be especially important for Charles-Haden Savage to appear in Season 4 considering that not only was Sazz his longtime stunt double and they maintained a unique friendship, but she was killed in his apartment at the end of Only Murders Season 3. So naturally Charles has a personal stake in solving this mystery, though he’ll still need the help of his true crime aficionado cohorts to get to the bottom of what happened.

Martin Short

Martin Short’s Oliver Putnam is back in Broadway’s good graces following the successful opening of Death Rattle Dazzle in the Season 3 finale, and much of that was him substituting for the lead role at the last minute. It remains to be seen if we’ll see him tackle another Broadway production during Season 4, though even if that’s the case, needless to say we won’t spend as much time following the making of the new play given. It’s also important to mention that Only Murders Season 4 taking place partially in Los Angeles will allow him to reunite with someone we’ll talk about shortly.

Selena Gomez

We found out our main trio of characters with Selena Gomez’s Mabel Mora. Unlike Charles and Oliver though, Mabel no longer lives at the Arconia, as her aunt sold the apartment and she moved out in “CoBro.” It still hasn’t been revealed where Mabel is living now, but obviously she’ll still be spending plenty of time at the building spending time with her older friends as they attempt to solve Sazz’s murder. We also have yet to see if Mabel will maintain a long-distance relationship with Jesse William’s Tobert in Season 4 since he moved to Los Angeles, or if their time together is over.

Meryl Streep

Only Murders in the Building Season 3 saw Oliver Putnam forming a romantic relationship with Loretta Durkin, one of the actresses he cast for Death Rattle Dazzle. Although there was a period where it seemed like Loretta might have been Ben Glenroy’s killer, that fortunately wasn’t the case, and by the end of the season, she was preparing to head to Los Angeles with Jeremy Shamos’ Dickie, her biological son, to pursue new professional opportunities. Well, good news for those of you who enjoyed Meryl Streep’s latest small screen performance, as she’ll continue recurring as Loretta in Season 4. I’d like to think this means that she and Oliver are still together, though it’s hard to tell going off of just the Only Murders Season 4 trailer.

Michael Cyril Creighton

After being a recurring character in the first two seasons of Only Murders in the Building, Michael Cyril Creighton’s Howard Morris was upgraded to the main cast in Season 3. It’s unclear right now if he’ll retain that status in Season 4 or be bumped back down to recurring, but either way, Howard will be back! Season 3 saw him working as Oliver’s assistant during the making of Death Rattle Dazzle., and we also learned how he had acting aspirations in his younger years. Unfortunately, it doesn’t seem like he’ll be traveling to Hollywood with Charles, Oliver and Mabel, so no auditions in Tinsel Town for him.

Da’Vine Joy Randolph

Every case in Only Murders in the Building has involved Detective Donna Williams in one form or another, and that won’t be changing in Season 4. While we don’t know yet if Da’Vine Joy Randolph’s character will be first on the scene to investigate Sazz Pataki’s death or if she’ll come into the proceedings later on, one thing we can count on is her getting fed up with Charles, Oliver and Mabel’s shenanigans pretty quickly.

Which Stars Are New For Season 4?

Molly Shannon

So far Molly Shannon is the only new addition to Only Murders in the Building Season 4 for whom any concrete character details have been shared. The Saturday Night Live alum is reportedly playing “a high-powered LA businesswoman who finds herself drawn into the world of the investigation in NY.” Now that the Only Murders Season 4 trailer has been released, it seems like she’s the driving force behind the movie about Charles, Oliver and Mabel’s podcast, as she needs them to sign over their life rights in order to make there project happen. Shannon’s other recent TV credits include being a series regular on Max’s The Other Two and Showtime’s I Love That For You, both of which have ended.

Eva Longoria

Eva Longoria will play a fictional version of herself in Only Murders in the Building Season 4, as she’s been cast to play Mabel Mora in the film adaptation of the Only Murders podcast. What’s unclear is if that will be the extent of her involvement this season or if she’ll be directly wrapped into the investigation. In addition to this Hulu series, Longoria, who also recently directed the Hulu movie Flamin’ Hot, also has Land of Women coming up, which will be streamable with an Apple TV+ subscription.

Eugene Levy

Way back in the day, Eugene Levy and Martin Short performed together on the sketch comedy series SCTV, and the two later appeared in Steve Martin’s Father of the Bride movies. Now Levy is finally getting to reunite with these two fellow comedic heavyweights thanks to Only Murders in the Building. In fact, the connection between them runs even closer on this series, as the fictional version of Levy will play Charles-Haden Savage in this Only Murders movie.

Zach Galifianakis

The list of comedic talents taking part in Only Murders Season 4 keeps growing, as Zach Galifianakis will also appear. Not only will his fictional self be playing Oliver Putnam in the Only Murders movie, it's been teased that he'll play an "integral" role in the investigation, though exactly how so remains to be seen Galifianakis, of course, is best known for playing Alan in the Hangover movies, but he's also well known for hosting Between Two Ferns and leading the TV show Baskets, as well as his roles in Birdman, The LEGO Batman Movie, A Wrinkle in Time and Ron's Gone Wrong.

Kumail Nanjiani

Kumail Nanjiani is also set to appear in a recurring capacity on Only Murders Season 4. Like with Eva Mendes and Zach Galifianakis, his character is also to be important to this season's investigation, though that still doesn't rule out him playing a fictional version of himself. Nanjiani's major credits from the last several years include Eternals, Migration, Obi-Wan Kenobi and Welcome to Chippendale's, the latter of which is also a Hulu-exclusive series. 2024 also see him starring in Ghostbusters: Frozen Empire.

Richard Kind

Yet another comedic heavyweight has joined Only Murders in the Building Season 4’s cast. This time, it’s Richard Kind, who has an impressive collection of both film and TV work, ranging from A Bug’s Life and A Serious Mind to Mad About You, Spin City and Curb Your Enthusiasm. No details about his role in the Hulu series have been revealed yet, though if I had to guess, he’s probably playing a character rather than a fictional version of himself. The eyepatch he's wearing certainly makes a strong case for this.

Daphne Rubin-Vega

In the world of stage acting, the Tony-nominated Daphne Rubin-Vega is best known for originating the roles of Mimi Marquez in Rent and Lucy in Jack Goes Boating, to name just a few of the productions she’s participated in. As far as her onscreen work goes, that includes the Jack Goes Boating film adaptation, In the Heights, Smash, Katy Keene and The Changeling. Whomever Rubin-Vega ends up playing in Only Murders in the Building, hopefully the role makes use of her singing talents.

Catherine Cohen

Acting-wise, Catherine Cohen has popped up in movies and TV shows like Broad City, The Lovebirds, Home Sweet Home Alone and What We Do in the Shadows. However, she’s best known for her 2022 Netflix comedy special The Twist...? She's Gorgeous, and her comedy act in general uniquely includes cabaret-style songs. It remains to be seen if that will factor into the character she plays on Only Murders in the Building.

Jin Ha

Jin Ha is another actor who’s built quite the resume of stage productions, most notable playing Aaron Burr in Hamilton on Broadway a few years back. But as far as TV work goes, his two main claims to fame are the Hulu miniseries Devs and the Apple TV+ series Pachinko. He also retimed with Devs creator Alex Garland for the movie Civil War. Now we wait to learn how he’ll fit into the events that unfold in Only Murders in the Building Season 4.

Melissa McCarthy

The Only Murders in the Building Season 4 trailer revealed that Melissa McCarthy will be along for the ride for this latest installment of the Hulu show. But in my continuing efforts to sound like a broken record, we don’t know yet if she’s playing a fictional version of herself or a separate character. Some of the actress’ recent appearances include Can You Ever Forgive Me?, Superintelligence, Thunderforce, The Little Mermaid and Unfrosted.

Keep your eyes peeled on this space for more casting updates about Only Murders in the Building Season 4, as you can count on the lineup of participating talent growing a lot bigger.
