Netflix Brings Alex North's 'The Whisper Man' to Screen With De Niro, Scott on Aug. 28

Netflix is ending August with what looks like its biggest original film of the season. The Whisper Man, an adaptation of Alex North's 2019 New York Times bestselling psychological horror novel, hits the platform on August 28, and if the cast list alone doesn't make you sit up, the pedigree behind the camera might.

Directed by James Ashcroft, the New Zealand filmmaker who made a serious impression with The Rule of Jenny Pen, the movie stars Robert De Niro, Adam Scott, and Michelle Monaghan. According to reporting by Deadline, it follows Tom Kennedy, a widowed crime writer who moves with his young son Jake to a quiet town called Featherbank, only to discover that a serial killer known as "The Whisper Man" once hunted children there. When Jake disappears under circumstances that mirror the old case, Tom has to turn to his estranged father, the retired detective who put the original killer away.

That's where De Niro comes in, playing Pete Kennedy, the father Tom hasn't spoken to in years. It's the kind of role where the estrangement does as much narrative work as the serial killer does. The script comes from Ben Jacoby, who wrote The First Omen, and Chase Palmer, who co-wrote It back in 2017. That lineage tracks. This is a book about grief and parenthood draped in horror-thriller clothing, and both of those writers know how to use genre to get at something rawer underneath.

The production company is AGBO, the outfit Anthony and Joe Russo built after their Marvel run. As reported by What's on Netflix, AGBO optioned North's novel back in June 2018, not long before the book even came out. This is the sixth film AGBO and Netflix have made together.

North told Netflix's Tudum that he wrote the book when his own son was around Jake's age, and that the father-son dynamic was always the emotional engine of the story. The serial killer plot is the mechanism. The real question the book keeps asking is what a parent passes on, and what they break. That's the kind of thing that, when it translates well to screen, makes for the sort of thriller you can't entirely shake.

According to Vital Thrills, the film carries an R rating for bloody violence, disturbing images, and language. That's appropriate. North's novel doesn't soften its horror, and Ashcroft's work has never been accused of being timid.

What's interesting here, beyond the movie itself, is what it represents in the ongoing book-to-screen pipeline. North's novel was a word-of-mouth hit that spread through crime fiction circles and eventually crossed into mainstream bestseller territory. The kind of book that readers pressed on their friends. That readership exists, it remembers the book, and Netflix is clearly betting it'll show up on August 28.

With De Niro at a point in his career where he's been making pointed choices about what he attaches his name to, and with Ashcroft establishing himself as someone worth watching, this one has more going for it than the average late-summer thriller drop. The source material earned its audience the old-fashioned way. Now we find out if the screen version does the same.
