Alan Ritchson announced at San Diego Comic-Con that Reacher Season 4 will debut on Prime Video on August 12. The new season adapts the thriller novel Gone Tomorrow, relocating the narrative from its original New York setting to Philadelphia, maintaining the show's practice of shifting locations and storylines with each instalment.

Production on Season 5 has already commenced, with filming approximately a week underway at the time of Ritchson's announcement, suggesting viewers should expect a relatively brief interval between seasons. Ritchson acknowledged the physical and creative demands of his workload, having completed or undertaken five additional film projects this year alongside the Reacher production, though he expressed continued commitment to the series despite the exhausting pace.
