‘I Will Find You’ Creators Reveal Major Villain Change and Shocking Ending Twist

Netflix’s I Will Find You takes some major risks by changing parts of Harlan Coben’s original novel, and the creators behind the series are explaining why those changes were necessary.

The thriller does not follow the book exactly. In Coben’s novel, readers discover important answers much earlier, including the identity of the villain and what happened to Matthew, the missing child at the center of the story. However, the Netflix adaptation keeps those mysteries hidden for much longer, creating a different experience for viewers.

According to Coben and show creator Robby Hull, the changes were made to make the story more suspenseful on screen. In an interview with ScreenRant, the two explained that they wanted audiences to experience the mystery alongside the main character instead of knowing key answers from the beginning.

One of the biggest changes involves Hayden, played by Milo Ventimiglia. The character becomes much more important in the series than in the original story, and part of that decision came from the actor’s performance.

Coben explained that Ventimiglia’s personality and acting ability influenced how they approached the character. He said the actor’s likability made the twist more powerful because viewers would not immediately expect him to be connected to the darker parts 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 hide 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 major difference between the book and the show is the mystery surrounding Matthew. In the novel, readers learn much earlier what happened to him. However, Hull explained that revealing too much too soon would hurt the television version of the story.

“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 said the goal was to make viewers feel the same confusion and desperation as David, the father searching for his missing son.

Hull explained that he and Coben wanted to create a stronger mystery by keeping the audience asking 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. The scene includes a powerful speech that was created specifically for the series.

Coben praised Stowe’s performance and said her presence helped make the moment more impactful. “You have an actress of Madeleine’s pedigree and abilities, and she just lights up the screen,” Coben said. Hull explained that the scene explores the complicated side of parenthood and the lengths people go to protect their children. “What happens when you try to protect them and it goes horribly, horribly wrong?” Hull said.

By changing parts of the original story, I Will Find You creates a different mystery while keeping the emotional themes that made Coben’s book popular. The creators believe these changes help the Netflix series deliver more surprises and stronger emotional moments for viewers.
