In Short

• The untitled spy series has received a straight-to-series order from Netflix

Actors Millie Bobby Brown and David Harbour, the on-screen father-daughter duo from Stranger Things, are set to reunite for a new untitled spy drama from creator Jack Thorne. In the series, Harbour will play Matt Wolfe, a disgraced former FBI agent turned security consultant, who is pulled back into the world he left behind when his estranged daughter Rebecca, played by Brown and now an FBI agent determined to follow in his footsteps, vanishes on a mission.

Netflix has given the spy drama a straight-to-series order. Jinny Howe, the company’s head of scripted series for the United States and Canada.

He was quoted by The Hollywood Reporter saying, "We are delighted to bring this spy drama to life with an extraordinary group of talent we’ve been fortunate to collaborate with before. Jack Thorne’s ability to find the deeply human story inside a thriller is unmatched, and watching Millie Bobby Brown and David Harbour reunite — this time as estranged father and daughter on opposite sides of a crisis — is something audiences are going to love. A24 is the perfect partner to bring this story to our members around the world."

Thorne, Harbour and Brown will also executive produce the series, alongside Jake Bongiovi and Robert Brown for PCMA Productions, Joe Hipps and Patrick McDonald for Cut To, which is based at A24, and KC Wenson for Bravo Axolotl.

The on-screen reunion comes six months after Stranger Things bowed out as Netflix’s biggest original series ever. In 2025, Harbour was the subject of a story in the UK tabloid the Daily Mail that claimed Brown had filed bullying and harassment claims against him. Harbour later said the “false” story caused him to have a breakdown.

Harbour, in an interview with Variety, said, "I don’t know if people have families and friends that you spend a lot of time with for 10 years — you occasionally get in arguments, disagreements. In families, it’s OK because you’re just in a disagreement, and then you come back together."

Brown also highlighted in a statement that over the course of Stranger Things’ five seasons, which spanned almost a decade, “our relationship became much more collaborative creatively” and that she had “a lot of gratitude” about their time on the series.

Brown will next be seen in Enola Holmes Season 3. The show will premiere on Netflix on July 1.
