‘Reacher’ Season 4 Book Origin & Cast Revealed: Here’s Everything to Know

Ahead of the premiere of Reacher‘s third season, Amazon Prime Video gave the action thriller an early renewal for Season 4, and now the series is back in production, with key details already coming through.

So what do we know about Reacher Season 4 so far? Here’s a look.

When will Reacher Season 4 premiere?

Amazon has not announced a release date for Reacher Season 4, but the streamer did announce the start of production in June. Chances are, Season 4 won’t premiere until sometime in 2026.

What book will Reacher Season 4 be about?

The next season will adapt the story in Gone Tomorrow, and the logline reads, “When a chance encounter with a distraught stranger on a train goes horribly wrong, Jack Reacher is drawn into a complex and deadly game that pits him against ruthless foes from the highest echelons of power.”

Gone Tomorrow finds Reacher embroiled in a major mystery after he witnesses a woman, who matches the description of a potential suicide bomber, die by suicide in front of him, leaving questions about her murky past as a Pentagon staffer.

The full description for the book reads, “New York City. Two in the morning. A subway car heading uptown. Jack Reacher, plus five other passengers. Four are okay. The fifth isn’t. And if you think Reacher isn’t going to get involved . . . then you don’t know Jack. Susan Mark, the fifth passenger, had a big secret, and her plain little life was being watched in Washington, and California, and Afghanistan—by dozens of people with one thing in common: They’re all lying to Reacher. A little. A lot. Or just enough to get him killed. A race has begun through the streets of Manhattan, a maze crowded with violent, skilled soldiers on all sides of a shadow war. For Jack Reacher, a man who trusts no one and likes it that way, the finish line comes when you finally get face-to-face and look your worst enemy in the eye.”

The first season was based on the debut novel, Killing Floor, which was chronologically the fifth book in the series. Then, Season 2 was based on Bad Luck and Trouble, which was the 11th book to be released and 14th in the chronology. The third season of Reacher was based on Persuader, the 11th book to be released and the seventh chronologically.

Who will star in Reacher Season 4?

Amazon has confirmed the cast for Season 4. Alan Ritchson will return to his role as Jack Reacher, and he will be joined by a slew of newcomers, including Jay Baruchel as Jacob Merrick, Sydelle Noel as Tamara Green, ANGEZ MO as Lila Hoth, Anggun as Amisha Hoth, Kevin Weisman as Russell Plum, Marc Blucas as John Samson, Kevin Corrigan as Detective Docherty, and Kathleen Robertson as Elsbeth Samson.

What else is there to know about Reacher?

In addition to renewing the action series for Season 4, Amazon also announced a series order for a Reacher spinoff, Neagley, which will feature Maria Sten returning to that role.
