The makers of the upcoming season of Reacher have announced the details regarding its initial cast and crew. The makers of Reacher Season 4 have welcomed eight new actors to its cast.
Reacher Season 4, which stars Alan Ritchson in the title role, is based on Gone Tomorrow , the thirteenth book in Lee Child ’s internationally acclaimed Jack Reacher novel series .
The show's description 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.”

New cast members joining Ritchson for Reacher Season 4 include: Jay Baruchel as Jacob Merrick, Sydelle Noel as Tamara Green, Agnez 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.
Baruchel will play Jacob Merrick, a small-town policeman. Noel will play Tamara Green, a detective with the Philadelphia Police Department. Mo will portray Lila Hoth, a young Indonesian woman who, along with her mother Amisha Hoth (Anggun), comes to Philadelphia to track down Lila’s American biological father. Corrigan will play Detective Docherty, Tamara’s partner.
Weisman will portray Russell Plum, a freelance journalist in Washington DC who has been surveilling a suspected CIA black site. Blucas will play John Samson, a U.S. Congressman, while Robertson will play his wife, Elsbeth Samson.
Reacher fans familiar with Gone Tomorrow may notice that the OTT series has tweaked some of the character names from the novel, with Merrick replacing Mark, Tamara swapping in for Theresa, Elspeth trading out the “p” for a “b” to become Elsbeth, and Svetlana becoming Amisha. The only major characters from Gone Tomorrow who remain to be cast for Season 4 are Susan Mark (likely Susan Merrick in the series) and Mr Springfield.
The streaming platform handed Reacher an early Season 4 renewal back in October 2024, four months before the third season premiered on the platform. It went on to become the biggest returning series in the streaming platform’s history.
The first three seasons of 'Reacher' are now streaming on OTT. A release window for Season 4 has not yet been announced.
