Netflix is teaming Millie Bobby Brown and David Harbour again for a new spy drama series, bringing the two Stranger Things actors back together in a fresh setting. According to Hollywood Reporter, the streamer has handed out a straight-to-series order for the untitled project from A24 and writer Jack Thorne. The series shifts the pair from Hawkins to the world of federal investigations, with a story built around a fractured father-daughter bond and a mission that goes badly wrong.

Millie Bobby Brown Plays Missing FBI Agent Rebecca

Actor Millie Bobby Brown will play Rebecca, an FBI agent determined to follow the same path as her father. That ambition drives the core of the series, but it also sets up the central crisis when she disappears during a mission. Her vanishing pulls the story into thriller territory fast, while also opening a family drama beneath the espionage plot. Rebecca is not just the person at the center of the case. She is also the reason an older generation is forced back into a world that no longer works the way it once did.

David Harbour Returns as Former Agent Matt Wolfe

Actor David Harbour will play Matt Wolfe, a disgraced former FBI agent who now works as a security consultant. His life changes when Rebecca, his estranged daughter, goes missing, forcing him back into the field he left behind. The setup gives the series a strong personal hook: a father trying to navigate both a dangerous investigation and a broken relationship. That dynamic could give the show more weight than a standard spy thriller, especially with two performers who already share years of on-screen history.

Jack Thorne and A24 Back the New Series

Writer Jack Thorne created the series and will executive produce alongside Brown, Harbour, Jake Bongiovi, Robert Brown, Joe Hipps, Patrick McDonald and KC Wenson. Netflix executive Jinny Howe framed the project as both a thriller and a character-driven drama. “We are delighted to bring this spy drama to life with an extraordinary group of talent we’ve been fortunate to collaborate with before,” said Jinny Howe according to Hollywood Reporter. A24’s involvement also adds another strong piece to the package as Netflix builds out its scripted slate.

Stranger Things Reunion Comes After Recent Rumors

The reunion arrives about six months after Stranger Things ended its run as Netflix’s biggest original series ever. That timing adds another layer to Brown and Harbour sharing the screen again, now in a much different relationship. The casting also follows recent tabloid claims about tension between the actors, which Harbour publicly pushed back on elsewhere. In this new project, the focus returns to their work together, with a story built on estrangement, urgency, and trust. For Netflix, it is a smart next move built around two familiar faces.
