The original "Secret Invasion" comic was an event that affected the whole Earth; the writers scaled the scope down and made it a spy thriller starring Nick Fury and Talos.
Principal photography ended in April 2022, but it was reported in June that the series is set to have four months of reshoots starting in mid July.
The producers cite the spy features Homeland (2011), The Americans (2013) and The Third Man (1949), the works of spy writer John le Carré and the Western movie The Searchers (1956) as an influence on the series.
