David Harbour says his next project with Millie Bobby Brown will build on the father-daughter chemistry that made Jim Hopper and Eleven central to Stranger Things while putting the actors inside a completely different story.
The former costars are reuniting for an untitled Netflix spy drama written by Adolescence writer Jack Thorne. Harbour will play disgraced former FBI agent Matt Wolfe, while Brown stars as his estranged daughter Rebecca, who followed him into the bureau before disappearing on a mission.
Harbour said the idea grew partly out of the feeling that Stranger Things could never completely satisfy everything viewers wanted from Hopper and Eleven’s relationship after five seasons.
Their new project will not continue those characters’ story, but Harbour believes the connection he and Brown developed over a decade of working together can carry into something new.

Speaking in a new Deadline interview, Harbour praised how Stranger Things creators Matt and Ross Duffer handled the show’s final season but said there was only so much room to resolve Hopper and Eleven’s relationship.
He and Brown wanted their next collaboration to preserve some of the chemistry viewers responded to between them, according to Entertainment Weekly. “It will surprise you,” Harbour said of the new series, describing it as “wild and rich” and filled with “deep emotion.” He also made his enthusiasm about reuniting with Brown clear, saying he loves working with her.
The New Series Replaces Hawkins With an FBI Mystery
Netflix officially announced the project in June, giving it a straight-to-series order rather than beginning with a pilot. Harbour’s Matt Wolfe is a disgraced FBI agent who has left the bureau behind and works as a security expert.
His estranged daughter Rebecca, played by Brown, has followed in his footsteps and become an FBI agent herself. When Rebecca disappears during a mission, Matt is pulled back into a profession that has evolved since he left it. A24 is producing the drama for Netflix, while Thorne will write and executive produce.
Netflix’s head of scripted series for the U.S. and Canada, Jinny Howe, said Thorne’s ability to locate a human story inside a thriller was central to the project and highlighted the appeal of seeing Harbour and Brown return as an estranged father and daughter facing a crisis together.
Brown Had Teased the Reunion Before Netflix Announced It
Brown began dropping hints about the project shortly before Netflix made it official. During a June 24th appearance on the Happy Sad Confused podcast, she said she and Harbour had “concrete” plans to work together again and suggested the collaboration would arrive sooner than people expected.
“Father-daughter is where we live, but Netflix will always be our home,” she said, according to Entertainment Weekly. Brown also revealed that the idea originated with Harbour. Both actors have publicly described the collaboration as something they actively wanted to continue after Stranger Things ended.
Brown and Harbour Are Executive Producers as Well as Stars
Brown and Harbour will both executive produce the untitled series. Brown’s husband, Jake Bongiovi, and her father, Robert Brown, are executive producing through PCMA Productions.
Joe Hipps and Patrick McDonald will executive produce for Cut To, while KC Wenson will do the same for Bravo Axolotl. Thorne comes to the project after the success of Adolescence, which he co-created with Stephen Graham. He has also previously worked with Brown’s Enola Holmes franchise, writing the first two films.
The Reunion Comes After Public Scrutiny of Their Offscreen Relationship
In November 2025, the Daily Mail published an unverified report alleging that Brown had filed a harassment and bullying complaint concerning Harbour before production on Season 5. The report said the allegations did not involve sexual misconduct.
Brown, Harbour and Netflix did not publicly confirm the reported complaint at the time. Harbour later acknowledged that he and Brown had experienced a disagreement during their years working together, but characterized it as an ordinary conflict within a long professional relationship rather than the dramatic rupture portrayed online.
He told Variety that once they were able to speak directly, the issue became a “simple rupture-and-repair.” Harbour also said that he and Brown “adore each other,” while Brown separately wrote that their working relationship had become increasingly collaborative as she grew up during the series.
