Prime Video has set the new cast joining star Alan Ritchson for the upcoming fourth season of flagship action drama Reacher, an adaption of Lee Child’s book series from showrunner Nick Santora, Amazon MGM Studios, Skydance Television, and CBS Studios.

Jay Baruchel (Fubar), Sydelle Noel (GLOW), Indonesian singer-actress Agnez Mo (Pernikahan), Indonesian-French singer Anggun (Levitating) and Kevin Corrigan (Poker Face) are set as series regulars and Kevin Weisman (Marvel’s Runaways), Marc Blucas (My Life with the Walter Boys) and Kathleen Robertson (The Expanse) as recurring guest stars in Season 4, which received an early renewal in October.

The new installment is based on the 2009 novel Gone Tomorrow, the 13th book in Child’s Jack Reacher series. In it, when a chance encounter with a distraught stranger on a train goes horribly wrong, Jack Reacher (Ritchson) is drawn into a complex and deadly game that pits him against ruthless foes from the highest echelons of power.

Baruchel will play Jacob Merrick, a small-town policeman. Noel will play Tamara Green, a detective with the Philadelphia police department. Mo will play Lila Hoth, a young Indonesian woman who, along with her mother, Amisha Hoth (Anggun), come to Philly to track down Lila’s American biological father. Corrigan will play Detective Docherty, Tamara’s partner.

Weisman will play 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. Robertson will play his wife, Elsbeth Samson.

With its third season, which premiered in February 2025, Reacher became the most watched returning series ever for Prime Video.

Santora, Child and Ritchson serve as executive producers alongside Don Granger, Scott Sullivan, Mick Betancourt, Lisa Kussner, Sam Hill, Amy Pocha & Seth Cohen, and David Ellison, Dana Goldberg, and Matt Thunell for Skydance.
