Millie Bobby Brown & David Harbour Reunite for New Thriller

Millie Bobby Brown and David Harbour are set to star in a new, untitled thriller series produced by A24 for Netflix. This project marks a notable reunion for the actors after their acclaimed run in the series Stranger Things.

David Harbour will embody Matt Wolfe, a disgraced FBI agent who transitions into a security expert role. Millie Bobby Brown is cast as Rebecca, an FBI agent who mysteriously vanishes while on assignment.

Both Brown and Harbour will also take on executive producer duties for the series. Since the conclusion of Stranger Things on December 31, Brown has been involved with Enola Holmes 3 and Harbour appeared in HBO's DTF St. Louis.

This collaboration follows a reported misunderstanding regarding a bullying complaint from 2025, which both actors have since clarified, emphasizing a positive and collaborative working relationship.
