Robert De Niro returns to crime territory in Netflix’s “The Whisper Man,” a thriller that arrives on Aug. 28, 2026, with the 81-year-old actor playing a retired detective pulled back into a case that never left him. The film pairs him with Adam Scott, Michelle Monaghan and Michael Keaton in a story built around grief, family estrangement and a killer who once operated in the dark just outside a child’s window.
De Niro plays Pete Cartwright, the estranged father of Tom Kennedy, a widowed crime writer played by Scott. When Tom is drawn into the hunt for a serial killer tied to his past, he turns to the father he has not been able to reach, and the two are forced into the same investigation. The setup gives De Niro another role built on a hard, guarded authority, the kind he helped define in crime films such as “Taxi Driver” and “The Irishman.”
The film is based on Alex North’s best-selling novel, which first debuted as a New York Times best-seller and centers on a serial killer known as The Whisper Man, a figure who lured victims by whispering at their windows at night. Ben Jacoby and Chase Palmer wrote the screenplay, and James Ashcroft directed the feature. Filming wrapped on June 4, 2025, setting the project on a long runway toward its late-summer release.
The release also marks the sixth collaboration between Netflix and AGBO, extending a partnership that has already produced five previous projects. That matters because the companies have settled into a rhythm that favors polished, high-concept genre work with built-in audience recognition, and “The Whisper Man” arrives with both a familiar title and a cast designed to broaden its reach.
What gives the film its edge is the tension between the case and the family at its center. This is not just another pursuit of a killer from the past. It is a story about a son who has to decide whether the man who raised him can still be trusted, and about a retired detective who may be the only person left who understands what the whispering meant. The August release date now sets the point when audiences will find out whether that uneasy bond holds.
