Reacher Season 4 dropped on Prime Video today, Wednesday August 12, at 3 AM Eastern with the first three episodes of an eight-episode season. Ritchson reportedly oversaw the fight choreography personally this season after feeling Season 2's action didn't match the books. Also landing on September 16, the same day as the Reacher Season 4 finale: Neagley, an all-eight-episode spinoff starring Maria Sten as Frances Neagley, Reacher's recurring ally from Special Investigators Unit days.
