Millie Bobby Brown and David Harbour will reunite as a father-daughter duo in a new A24 spy series for Netflix [1, 2].

The pairing marks a return to the familial dynamic the actors established in "Stranger Things," leveraging their established chemistry for a high-stakes thriller. This collaboration signals a continued effort by Netflix to pair proven stars in genre-bending content produced by A24.

According to reports released Friday, the series is written by Jack Thorne [1, 2]. The plot focuses on the relationship between Matt Wolfe and his estranged daughter, Rebecca [1, 6]. Harbour will portray Wolfe, a disgraced FBI agent, while Brown will play Rebecca, an FBI agent who disappears during a mission [1, 6].

The narrative centers on the fallout of Rebecca's disappearance, which forces the disgraced father to return to field work to find her [1, 2]. While the actors previously played a surrogate father-daughter pair, this project moves them into a professional intelligence setting, a departure from the supernatural elements of their previous work together [4].

Production details regarding the release date have not been disclosed, though the project is confirmed as a Netflix series [1, 3]. The project brings together the prestige branding of A24 with the global reach of the streaming platform [1, 2].

This casting strategy suggests Netflix is leaning into 'proven chemistry' to mitigate the risk of new intellectual property. By pairing Brown and Harbour in a grounded spy thriller, the studio can attract both the existing fanbase of their previous collaborations and a broader audience interested in A24's specific cinematic style.
