Project Summary
Millie Bobby Brown and David Harbour are reuniting for an untitled spy thriller series that has received a straight-to-series order at Netflix. Created and written by Jack Thorne, the Emmy-winning writer behind Adolescence and the Enola Holmes films, the series follows Matt Wolfe, a disgraced FBI agent turned security consultant, who is drawn back into the espionage world when his estranged daughter Rebecca—now an FBI agent determined to follow in his footsteps—vanishes on a mission. The project is produced by A24 in partnership with Cut To and PCMA Productions, with Brown and Harbour both serving as executive producers alongside Jake Bongiovi, Robert Brown, Joe Hipps, Patrick McDonald, and KC Wenson. Production is targeting a late 2026 start, with Netflix eyeing a 2027 premiere for the eight-episode first season.
