The Whisper Man Features Netflix's Finest Cast Yet

A New Psychological Thriller from Netflix

Fans of Mindhunter and Mare of Easttown are in for a treat with Netflix’s upcoming psychological thriller, which boasts one of the streaming service's most impressive casts ever. Netflix has made a name for itself by bringing back the psychological thriller genre in recent years. The 2021 hit The Chestnut Man calls to mind classic '90s serial killer thrillers like Se7en, The Cell, Along Came A Spider, The Silence of the Lambs, Copycat, The Bone Collector, and Taking Lives. These films share a common thread: a twisted serial killer with a unique, unsettling modus operandi.

Netflix's earlier hit Mindhunter, based on the non-fiction book Mindhunter: Inside the FBI's Elite Serial Crime Unit, delved into the history of criminal profiling in a way that was both fascinating and unsettling. Although based on real-life criminal investigations undertaken by the FBI’s Behavioral Science Unit, Mindhunter felt just as tense, dramatic, and terrifying as any fictional story of criminal profiling like Hannibal or Criminal Minds.

Given this track record, it shouldn't come as a surprise that one upcoming Netflix movie, The Whisper Man, is now set to blend the stories of Mare of Easttown and Mindhunter in its chilling plot. Based on the novel of the same name by author Alex North, The Whisper Man follows Tom Kennedy, a crime writer who seeks the help of his father, retired Detective Inspector Pete Willis, to investigate the abduction of his son.

A Dark Story That Maintains Netflix's Best Psychological Thriller Trend

North’s book was published in 2019, and its dark story blends character drama with twisty psychological thriller plotting to great effect. Netflix’s earlier hit psychological thrillers You, Mindhunter, The Hunting Wives, and His & Hers were all also based on bestselling books, which makes the upcoming project all the more appealing. However, the real selling point of this mashup between Mindhunter and Mare of Easttown is its staggering cast.

Hokum star Adam Scott leads The Whisper Man as the widowed author Tom Kennedy, meaning the movie marks his second time playing a troubled writer with a dark past in 2026. Robert De Niro plays Detective Inspector Pete Willis, while Michelle Monaghan plays Detective Amanda Beck. As if this weren’t enough star power for one project, The Whisper Man’s supporting cast includes Michael Keaton, John Carroll Lynch, Hamish Linklater, and Owen Teague.

Known for their standout roles in everything from Zodiac to Midnight Mass, this ensemble cast ensures The Whisper Man isn’t resting on the fame of its central stars. That said, one of De Niro’s earlier Netflix projects was Martin Scorsese’s The Irishman, a mob epic that remains one of the streaming service’s most critically acclaimed movies ever. This, combined with the considerable pedigree of The Whisper Man’s director, marks the upcoming movie out as something truly special.

A Star Can Redeem a Major Netflix Flop

The Whisper Man’s director, James Ashcroft, most recently directed 2021’s Coming Home in the Dark and 2024’s The Rule of Jenny Pen, both based on short stories by the celebrated New Zealand writer Owen Marshall. Both movies are dark, gripping psychological thrillers that are not for the faint of heart, exploring themes of political corruption, institutional abuse, and generational trauma with a bracing brutality that goes far further than most Hollywood horror movies.

This means viewers can expect The Whisper Man to take no prisoners, which will be a big relief for anyone who remembers De Niro’s most recent Netflix project, Zero Day. A comically misguided political thriller, Zero Day was goofy, outlandish, and painfully slow. Like a bizarre mashup of The West Wing and The Day of the Jackal, the show starred De Niro as an aging former President who is tasked with identifying the nefarious criminals behind the titular terror attack.

Where most conspiracy thrillers focus on underprepared, powerless characters who are caught up in a web of lies, as seen in Three Days of the Condor, The Parallax View, and Arlington Road, Zero Day took the opposite approach entirely and expected viewers to worry about one of the most powerful people on the planet. With a frankly astounding supporting cast that included Lizzy Caplan, Dan Stevens, Angela Bassett, Joan Allen, Clark Gregg, Jesse Plemons, Connie Britton, and Matthew Modine among many, many others, Zero Day was a truly historic waste of talent.

Thus, The Whisper Man could prove to be De Niro’s next great Netflix project after this critical and commercial disappointment. The project’s chosen format and runtime also bodes well, as The Whisper Man breaks with a major Netflix psychological thriller tradition to offer viewers something new in the genre. Unlike most of Netflix’s biggest recent psychological thriller hits, The Whisper Man is a movie rather than a miniseries.

A Major Change to Netflix's Reliable Psychological Thriller Formula

The almost unbearable tension of Coming Home in the Dark and The Rule of Jenny Pen would have been far harder to sustain over a longer runtime, and many viewers would likely have given up on these pitch-black thrillers if they were multi-episode shows. As such, the news that Netflix’s next big psychological thriller is a standalone movie rather than a show is a welcome change. Many of the best psychological thrillers of recent years have been self-contained miniseries adaptations of novels, from Prime Video’s The Girlfriend to Netflix’s own Alice Feeney series His & Hers.

However, The Whisper Man’s story calls to mind the aforementioned earlier era of serial killer thriller movies that peaked in popularity during the ‘90s, and, for the project to truly recapture the appeal of cult classics like Frailty, Cure, and Fallen, the shorter, punchier runtime of a movie is a necessary ingredient. Furthermore, The Irishman’s success and Zero Day’s failure prove that De Niro’s performances could be better suited to movies.

The Whisper Man might not live up to the obvious potential of this creepy whodunit’s killer premise. However, with Scott and De Niro leading the adaptation and Ashcroft behind the camera, the movie has the opportunity to be an enthralling serial killer thriller for the streaming generation. If the back catalog of its stars, original author, and director is anything to go by, The Whisper Man may take the building blocks of Mare of Easttown and Mindhunter and fashion them into Netflix’s best standalone psychological thriller movie yet.
