A sense of foreboding will be your plus-one when you attend Netflix’s Something Very Bad is Going to Happen.

Ross and Matt Duffer, the producers behind the mega-hit series Stranger Things are producing the series which was created and written by Haley Z. Boston, who has written for Netflix before on the series Brand New Cherry Flavor and Guillermo del Toro’s Cabinet of Curiosities. Also producing is Hilary Leavitt, via their Upside Down Pictures overall deal with Netflix.

The series’ official logline says the name of the show gives nothing away. “Something Very Bad Is Going To Happen is an atmospheric horror series set at a wedding, following a bride and groom in the week leading up to their ill-fated nuptials. That’s not a spoiler – just read the title…”

“We were knocked flat when we first read Haley’s script. She is a major new talent with a singular voice — her writing is twisted, terrifying, funny, and just… very Haley,” the Duffer Brothers said in a statement. “We feel so lucky to be producing her first show, and we can’t wait to share her vision with the rest of the world.”

News of the series order comes one day after Netflix revealed a first look at the final season of Stranger Things, revealing new cast members Nell Fisher, Alex Breaux and Jake Connelly. Production on the last episodes is about halfway done and though no premiere date has been set, the season is expected to drop in 2025. The Duffer Brothers are also involved with the stage play Stranger Things: The First Shadow, which debuted in London’s West End in December.
