‘I Will Find You’ Creators Discuss Major Villain Change and Shocking Ending Twist
Netflix’s ‘I Will Find You’ takes significant risks by altering elements of Harlan Coben’s original novel, and the creators of the series are sharing their reasoning behind these necessary changes.
The thriller diverges from the book in key ways. In Coben’s novel, readers uncover vital answers much sooner, including the identity of the villain and the fate of Matthew, the missing child at the heart of the story. However, the Netflix adaptation keeps these mysteries concealed for a longer duration, offering viewers a different experience.
According to Coben and show creator Robby Hull, these alterations were made to enhance the suspense on screen. In an interview with ScreenRant, they explained their desire for audiences to unravel the mystery alongside the main character instead of having crucial answers revealed early on.
One of the most significant changes involves Hayden, portrayed by Milo Ventimiglia. The character holds a far more crucial role in the series than in the original narrative, a decision influenced by the actor’s compelling performance.
Coben noted that Ventimiglia’s charm and acting skills shaped their approach to the character. He remarked that the actor’s likability amplifies the impact of the twist, as viewers would not immediately suspect him of being linked to the darker aspects of the story.
“Besides being a fantastic actor, when you get someone like that, you want to give him more and more and more,” Coben told ScreenRant. “He’s so lovable, he’s so likable as a human being in real life, I think maybe why this worked so well.”
The author added that casting Ventimiglia allowed the team to cleverly conceal the villain in plain sight. “How lucky for us that we’re able to hide the villain behind that face,” Coben said. “When we do pull the rug out from under you, it has that much more emotional impact.”
Another significant difference between the book and the show is the mystery surrounding Matthew. In the novel, readers learn much sooner what happened to him. However, Hull explained that revealing too much too early would detract from the television adaptation.
“In the book, you sort of know where Matthew is early on, because you’re in these characters’ heads,” Hull explained. “Translating it to the screen, you don’t want to give that up.” The showrunner emphasized that the aim was to evoke the same confusion and desperation felt by David, the father searching for his missing son.
Hull explained that he and Coben sought to create a more compelling mystery by keeping the audience engaged with the same questions as the main character. “The audience should be with your character, which is, we don’t know where Matthew is,” Hull said. “Let’s hide him, let’s figure out a different way than the book went.”

The creators also discussed the emotional final confrontation between Hayden and his mother Gertrude, played by Madeleine Stowe. This scene features a powerful speech crafted specifically for the series.
Coben praised Stowe’s performance, noting that her presence significantly enhances the moment’s impact. “You have an actress of Madeleine’s pedigree and abilities, and she just lights up the screen,” Coben said. Hull added that the scene delves into the complex nature of parenthood and the lengths one might go to protect their children. “What happens when you try to protect them and it goes horribly, horribly wrong?” Hull pondered.
By modifying elements of the original story, ‘I Will Find You’ creates a distinct mystery while retaining the emotional themes that made Coben’s book beloved. The creators believe these adjustments enable the Netflix series to deliver more surprises and stronger emotional moments for its audience.
