Millie Bobby Brown and David Harbour reunite for Netflix spy series after 'Stranger Things'

Millie Bobby Brown and David Harbour are officially reuniting on screen after the end of Stranger Things, with Netflix ordering a new untitled spy drama that will see the pair once again play a father-daughter duo.

The series, which has received a straight-to-series order, comes from Emmy-winning writer Jack Thorne (Adolescence, Enola Holmes) and A24. Brown and Harbour will not only star in the project but also serve as executive producers.

According to Netflix, Harbour will play Matt Wolfe, a disgraced FBI agent turned private security expert who is forced back into the world of espionage when his estranged daughter Rebecca, played by Brown, disappears during an FBI mission. The high-stakes thriller follows Wolfe as he navigates a vastly changed intelligence landscape in a desperate bid to save his daughter.

The project marks Brown and Harbour's first collaboration since Stranger Things concluded in 2025, where they portrayed Eleven and her adoptive father, Jim Hopper. Their on-screen relationship became one of the most beloved aspects of the Netflix hit across its five-season run.

The announcement comes just days after Brown teased that she and Harbour were already planning another project together. Speaking on the Happy Sad Confused podcast, she revealed that the pair would once again be playing a father and daughter, calling the collaboration "sooner than expected".

Netflix's Head of Scripted Series for the US and Canada, Jinny Howe, praised the creative team behind the new drama, saying Thorne has a unique ability to find "the deeply human story inside a thriller". She added that audiences would love seeing Brown and Harbour reunite as "estranged father and daughter on opposite sides of a crisis".

The series also reunites Brown with Thorne, who wrote both Enola Holmes films, while continuing Harbour's long-running relationship with Netflix following Stranger Things. Executive producers include Brown's husband Jake Bongiovi and her father Robert Brown through PCMA Productions.

No title or release date has been announced, but the untitled spy thriller joins Netflix's growing slate of prestige dramas as Brown and Harbour prepare to begin their next chapter together beyond Hawkins.
