Sam Worthington and Britt Lower Lead an Ensemble Cast in Netflix’s New Harlan Coben Thriller ‘I Will Find You’

Netflix’s newest Harlan Coben adaptation is arriving with a cast built to carry a story about wrongful conviction, grief, and a father’s desperate search for answers. The eight episode series, adapted by showrunner Robert Hull from Coben’s 2023 novel, follows Sam Worthington as David Burroughs, a man wrongfully serving a life sentence for the murder of his son. Worthington stars alongside Britt Lower, Milo Ventimiglia, and Erin Richards, with the series slated to premiere on June 18, 2026.

The cast of ‘I Will Find You’ was assembled gradually over the course of last year, with new names joining the project through the spring of 2025. Worthington was first announced as the lead in March 2025 alongside Lower, Ventimiglia, Richards, and Logan Browning, with Jonathan Tucker joining the production a month later. By the time filming wrapped, the show had pulled together actors known for prestige drama, blockbuster action, and longtime network television.

The Cast of ‘I Will Find You’ Brings Together a Recognizable Ensemble

Worthington stars as David Burroughs, the father at the center of the story, while Lower plays Rachel Mills, David’s former sister in law and a once decorated reporter whose career collapsed after she was fired. Lower’s casting drew particular attention given her recent run on ‘Severance,’ a role that has made her one of the more closely watched actors on television right now.

Ventimiglia plays Hayden, Rachel’s ex boyfriend who remains one of her closest confidants, while Richards rounds out the central four as Cheryl Dreason, David’s ex wife and a pediatric surgeon. Chi McBride also appears across all eight episodes as Max Williams, and Logan Browning plays Sarah Greer, a member of the FBI’s Fugitive Task Force in Boston.

McBride’s character is described as a legend within that same Fugitive Task Force, the agent tasked with pursuing David no matter the personal cost. That dynamic, an experienced lawman chasing a father who insists he is innocent, gives the series its central pursuit structure.

Sam Worthington’s Role as a Father Determined to Prove His Innocence

In the series, David is shown a recent photo by Rachel that appears to prove his son Matthew, played by Ashton Cressman, is still alive. That revelation sends David out of prison and into a world of deceit, forcing him to clear his own name while racing to find his son before it is too late.

Worthington’s casting fits a pattern that has defined Coben’s Netflix run, where ordinary people are pulled into extraordinary circumstances built around family and grief. The actor, long associated with large scale studio work, brings a more grounded and physical register to a character defined by desperation rather than heroics.

Lower’s Rachel becomes David’s primary partner in the investigation, and the two characters drive most of the series’ momentum together. Lower has described the project as centered on how far a person will go to protect someone they love, a framing that puts emotional stakes ahead of straightforward procedure.

The Supporting Cast and Guest Stars Expanding the Mystery

Jonathan Tucker plays Adam Mackenzie, a police sergeant and David’s best friend, while Madeleine Stowe joined the cast as Gertrude Payne, a wealthy heiress harboring a dark secret. Clancy Brown also stars as Nicky Fisher, a semi retired, old school mobster whose ties to the Burroughs family threaten to expose secrets that have stayed buried for years.

Vas Saranga rounds out the principal additions as Agent Dev Chopra, while a long list of guest performers fill out the world around David and Rachel, including Hugh Thompson, Peter Outerbridge, Christopher Redman, Eric Johnson, Greg Bryk, Kate Vernon, Tara Rosling, Darrin Baker, Aaron Ashmore, Nicola Correia Damude, Rachel Wilson, and Billy MacLellan. Baker’s character, Jim Doherty, appears in five episodes, while Saad Siddiqui plays Dimitri across four.

The breadth of the supporting cast reflects the scope of the mystery itself, which pulls David and Rachel through prison walls, law enforcement circles, and a wealthy family with its own history to hide. Each new character adds another thread to a plot built around long buried secrets rather than a single obvious villain.

Harlan Coben’s Netflix Adaptation Took Shape Over Months of Production

Robert Hull, known for his work on ‘Quantum Leap’ and ‘Alcatraz,’ co-created the series with Coben and serves as showrunner, while Coben acts as executive producer through his Final Twist Productions alongside Hull, Bryan Wynbrandt, Steven Lilien, and John Weber. It marks the first time one of Coben’s novels has been adapted by Netflix with an American setting rather than the author’s usual European backdrop.

According to Tudum, Hull said the cast assembled for the project was “nothing short of phenomenal,” adding that any one of the actors involved would have been a draw on their own.

Filming took place across Kingston and Toronto, Ontario, from April through August 2025, with key scenes shot inside Kingston Penitentiary and on the University of Toronto Mississauga campus. Additional scenes were captured in New York City in late August 2025, including locations around Washington Square Park, Central Park, and Times Square.

Directing duties on the eight episode series were split among Brad Anderson, Maja Vrvilo, Adam Davidson, and Maggie Kelly. Coben has said the novel was written alongside the television adaptation for the first time in his career, noting that he and Hull shared a vision for a story meant to grip viewers before landing an emotional finish.

With production wrapped and all eight episodes ready to stream, the cast of ‘I Will Find You’ is set to test whether Coben’s latest setup, an innocent father racing to find a son everyone believes is dead, can match the pull of his earlier Netflix hits.
