Netflix crime thriller film The Whisper Man will premiere on Friday, August 28, 2026, featuring a star-studded cast led by Robert De Niro.
The 111-minute film follows widowed crime novelist Tom Kennedy, played by Adam Scott, whose eight-year-old son Jake disappears mysteriously from his home. Desperate for help, Tom contacts his estranged father Pete Willis, a retired police detective inspector portrayed by De Niro, who captured a serial killer known as the Whisperer two decades earlier.
Together, the father and son must determine whether the young boy was taken by a copycat offender or an accomplice, while the original murderer remains behind bars. The narrative centers on their efforts to locate Jake while attempting to rebuild their fractured family relationship.
The movie is an adaptation of author Alex North's bestselling novel of the same name, which reached the New York Times bestseller list. Director James Ashcroft, known for helming The Rule of Jenny Pen and Coming Home in the Dark, directs the project from a screenplay written by Ben Jacoby and Chase Palmer. Jacoby previously wrote The First Omen, while Palmer co-wrote the horror film It.
The production is backed by a veteran producing team that includes Anthony Russo, Joe Russo, Angela Russo-Otstot, and Michael Disco. The Russo brothers are widely recognized for producing major Hollywood blockbuster features through their production endeavors.
