Millie Bobby Brown and David Harbour are reuniting for a new Netflix spy series, six months after Stranger Things concluded as Netflix’s biggest original series ever.
In the untitled show, Harbour will play Matt Wolfe, a disgraced former FBI agent turned security consultant, while Brown portrays his estranged daughter Rebecca — an FBI agent who vanishes on a mission, pulling Wolfe back into the world he left behind.
A New Chapter for the Stranger Things Stars
The series, created by Jack Thorne (Adolescence, Enola Holmes) and produced by A24, marks the first time Brown and Harbour will share the screen since Stranger Things wrapped its five-season run. Their onscreen chemistry helped define one of Netflix’s most successful originals.
Netflix’s head of scripted series for the U.S. and Canada, Jinny Howe, said the streaming platform was “delighted to bring this spy drama to life” with the pair, praising Thorne’s ability to “find the deeply human story inside a thriller.”
Both stars will executive produce alongside Jake Bongiovi and Robert Brown for PCMA Productions, Joe Hipps and Patrick McDonald for Cut To (based at A24), and KC Wenson for Bravo Axolotl.
From Set Tensions to Shared Goals
The reunion comes after a turbulent period. Harbour was the subject of a 2025 Daily Mail story alleging bullying claims by Brown — claims he called “false” and said caused him to have a breakdown. In a recent interview with Variety, Harbour reflected on long-term collaborations, saying: “In families, it’s OK because you’re just in a disagreement, and then you come back together.”
Brown also shared her perspective, noting their relationship evolved creatively over Stranger Things’ nearly decade-long run and expressing “a lot of gratitude” for their time on the series.
Production details, including start dates and release windows, remain unconfirmed. But with Thorne at the helm and A24 on board, the project signals a bold new direction for both actors beyond Hawkins.
