‘Only Murders in the Building’ Season 4: Everything to Know About the Next Whodunnit

When Is 'Only Murders' Season 4 Coming Out?

Hulu announced Only Murders in the Building was renewed for season four on Oct. 3, the day season three released its final episode. Since the renewal is still fresh, there isn’t any news about a release date for its next installment yet, but summer 2024 might be a safe-ish bet since every season of the show has premiered in the summer. However, while the writers strike might be over, the actors strike continues, which could potentially delay season four’s release. Rest assured, though, the Only Murders in the Building writers room opened Oct. 9, Hoffman told THR, so as soon as the studios and the actors union come to an agreement, the show will be able to begin production.

Who Will Be in 'Only Murders' Season 4?

News is starting to trickle in about the cast. The first thing fans could take comfort in is knowing the show’s core trio — Mabel, Charles and Oliver — will be returning, without a doubt. Despite season three’s devastating loss of Sazz, Lynch will be back, most likely in flashbacks, similar to how Rudd’s Ben had a role in season three despite dying in the first episode.

Meryl Streep and Jesse Williams both joined the show’s third season, as well as a few other new faces. Co-creator Hoffman told THR after last season ended that there was “no greater hope for me” than bringing the two of them back: “I love them both, Jesse and Meryl, everyone. I mean, for God’s sakes, I would bring Paul back if we can. Listen, I would bring everyone back, and that might happen. Victims, killers, they’re all able to play in the landscape within this sort of certain narrative ways we can tell our stories.”

Now it’s been confirmed that Streep will indeed be returning. The Oscar-winning actress will reprise her role as Loretta Durkin, the love interest to Short’s Oliver Putnam. Season three ended with Loretta getting an offer to work in Los Angeles.

Other castmembers who are likely to return to season 4 in some capacity are Michael Cyril Creighton’s Howard, Ryan Broussard’s Will, Jackie Hoffman’s Uma, Da’Vine Joy Randolph’s Detective Dee Williams, Jason Veasey’s Jonathan and James Caverly’s Theo. While Nathan Lane’s Teddy Dimas wasn’t in season three due to scheduling conflicts, he has said he’s open to returning to the series if he’s able to. Hopefully, Tina Fey’s Cinda Canning will come back as well, though her role in season three was pretty limited — only appearing in one episode to try to convince Mabel to join her podcast.

In February, news broke that Molly Shannon is joining Only Murders in the Building season 4. She will play a high-powered, Los Angeles businesswoman, who finds herself drawn into the world of Sazz’s murder investigation in New York. Not much else is known about her role.

Shannon may have been the first new castmember announced for this season, but Eva Longoria, Eugene Levy, Kumail Nanjiani and Zach Galifianakis’ castings quickly followed. Like Shannon’s character, Longoria, Levy and Nanjiani’s roles are being kept under wraps, but they will all be integral to the twists and turns of season four’s investigation.

What Will 'Only Murders' Season 4 Be About?

As with every other season, the final moments of season three revealed whose murder the trio will be investigating in season four. This time around, Mabel, Charles and Oliver will have to find who killed their beloved friend and Charles’ longtime stunt double, Sazz. Only Murders in the Building executive producer Jess Rosenthal suggested Sazz be the person who gets murdered, and Hoffman immediately lit up at the idea. He told THR he thought it was simultaneously “awful” and “perfect.”

“I immediately, it’s the thing of like, if we get a chance to go more, it’ll be the thing that it just started exploding ideas in my head,” he said. “So, that was thrilling. And then the second part of that was actually talking to Jane Lynch about it and saying, ‘This is what we’re thinking.’ We had to do that pretty early, too, and that was very sweet. She was like, ‘I love it.'”

At the very end of the final episode of season three, as Sazz was dying, it looked like she was trying to write something on Charles’ kitchen floor with her own blood. What that is is unknown, but it will certainly come up in the next installment of the show. Hoffman explained that during production, there were discussions about how long to hold the shot of her trying to write something and how long to have her finger moving for. They decided to keep it as abstract as possible for now in order to keep their options open for the fourth season.

“It feels very in her character to send a message,” he continued. “She’s been trying to do it to Charles throughout the season. She’s hinting to him in episode five that she’s picking up some ham radio chatter, certainly, right when she arrives in the finale, she’s saying, ‘Can I grab you for a few minutes? It’s a little sensitive.’ So, there’s something on her mind and something she may know but to be found out.”

As for who may have wanted to kill Charles — if that’s what they were trying to do — is also still up in the air. Hoffman played coy, only sharing that there’s a lot of exploring to do down that road. One thing they had in mind when thinking of season four’s victim was wanting to choose someone who is close to someone in the trio because the more personal it is to one of them, the better. Sazz’s death felt like an opportunity to make the victim someone Charles was close to and explore their connection.

“We’ve loved writing Sazz so much, and that’s the beauty of the show is, you get a lot more time with the victims,” Hoffman said. “They’re not gone when some ill fate happens to them. And that’s, I think, also why Jane said she was excited because it’s a good opportunity to go deeper with Sazz and find out what the whole big life and everything else was with her and the world of stunt doubling.”
