Confirmed Cast and Characters

Who Plays Lazarus in the TV Series?

Sam Claflin takes on the titular role of Lazarus in the Prime Video series, delivering what reviewers have characterized as a compelling performance in a psychologically complex character. The actor, perhaps best known for his work in The Hunger Games franchise and the romantic drama Me Before You, embraces a significantly different register for this role as a forensic psychologist confronting his family’s darkest secrets.

In interviews leading up to the premiere, Claflin spoke extensively about his collaboration with Harlan Coben, describing the experience as uniquely challenging given the psychological depth required for the character. The TODAY show appearance featured both Claflin and Coben discussing their creative partnership and the series’ blend of mystery and supernatural elements.

Beyond his work as an actor, Claflin holds an executive producer credit on the project, indicating substantial creative investment in the series. His portrayal of Laz requires navigating the character’s return to his family home, his investigation into cold-case murders, and his gradual uncovering of supernatural truths that challenge his professional understanding of reality.

Claflin’s Approach to the Role

The character of Laz presents unique demands that distinguish it from Claflin’s previous screen work. As a forensic psychologist, the character applies clinical analysis to cases that progressively intersect with inexplicable phenomena. This creates an internal tension between scientific methodology and supernatural discovery that Claflin has described as central to his performance approach.

The narrative structure also requires Claflin to portray the character across different life stages, with Ewan Horrocks handling the younger Laz sequences. This parallel performance adds dimension to the character’s journey, allowing viewers to understand the formative experiences that shape the adult protagonist’s worldview and vulnerabilities.

What Characters Do the Cast Play?

The character dynamics in Lazarus center on family relationships complicated by secrets, loss, and the lingering effects of past tragedies. The central narrative follows Laz’s return to his family home and his investigation into murders that directly involve his relatives, creating an intimate web of suspects, witnesses, and victims who are all connected through blood ties.

Central Characters

Laz (Sam Claflin) serves as both investigator and subject in the mystery. His forensic psychology background provides the professional framework through which he approaches the cold cases, yet his personal connections to the events force him to balance objectivity with emotional investment. The character’s journey represents a confrontation with family history that he has likely spent years trying to escape.

Jenna Lazarus (Alexandra Roach), Laz’s sister, occupies a crucial position within the narrative. Her connection to the central mysteries suggests that the family secrets extend across generations, with Jenna potentially holding key information that shapes the investigation’s direction. The character appears to represent the family member who remained connected to their shared history while Laz pursued his career elsewhere.

Dr. L (Bill Nighy) operates as a significant figure whose relationship to the protagonist and the broader mystery remains central to the series’ unfolding revelations. Nighy’s casting brings considerable gravitas to the role, with the actor’s extensive experience lending weight to whatever revelations his character provides or withholds.

Young Laz (Ewan Horrocks) appears in sequences depicting the protagonist’s earlier life, establishing formative experiences that inform the adult character’s psychology. These flashback elements contribute to understanding how Laz developed his investigative instincts and what childhood events shaped his relationship with his family and hometown.

Supporting Characters

Seth McGovern (David Fynn) and Bella (Karla Crome) round out the primary ensemble, providing additional perspectives on the community where the mysteries unfold. Their specific roles within the narrative extend beyond simple supporting functions, as both characters appear connected to the events that Laz investigates.

What Is the Lazarus TV Show About?

Lazarus unfolds as a mystery thriller that combines procedural investigation with supernatural elements, creating a genre blend that distinguishes it from conventional crime dramas. The series follows forensic psychologist Laz as he returns to his family home after his father’s death, only to find himself drawn into cold-case murders that have haunted the community for years.

The investigation quickly becomes personal when Laz discovers connections between the unsolved cases and his own family, including his sister Jenna. As he digs deeper into the historical crimes, the series introduces elements that challenge the protagonist’s scientific worldview, suggesting that the truth behind the murders extends beyond rational explanation.

This combination of psychological investigation and supernatural discovery creates a distinctive tonal balance. According to Rotten Tomatoes coverage, the series leverages its mystery-thriller framework to explore themes of family loyalty, inherited trauma, and the limits of rational understanding when confronting inexplicable events.
