Lazarus Season 1 complete cast breakdown: Who plays who & where you’ve seen them before

Harlan Coben’s Lazarus Season 1, a gripping six-episode thriller, premiered on October 22, 2025, on Amazon Prime Video. Co-created with Danny Brocklehurst (Fool Me Once, Stay Close), this marks Coben’s first original TV series unbound by his novels.

Produced by Quay Street Productions, Amazon MGM Studios and Final Twist Productions, it was filmed in northern England, starting in February 2024, capturing a bleak and authentic atmosphere. The story follows Joel "Laz" Lazarus, a London-based forensic psychologist who returns to his hometown after his father, Dr. Jonathan Lazarus, dies by apparent suicide.

 
Laz is plagued by graphic images of violent murders, including his sister's unsolved murder from 25 years ago, so he decides to investigate cold cases to see if he is losing his mind. His sister, Jenna, discovers family secrets that suggest an undercurrent of supernatural influences, balancing the psychological drama aspect of the show with a twisty narrative, reminiscent of a Coben touch.

Partly directed by Wayne Che Yip (The Responder, The Rings of Power), the series explores grief, fractured relationships and trauma that resurfaced after many years. The early reviews praise the raw performances from the ensemble cast, but point out that the pacing slows somewhat in later episodes.
