Two new stars have joined Robert De Niro inThe Whisper Man. The upcoming Netflix feature, which adapts the novel of the same name by Alex North, follows a man whose 8-year-old son is abducted, forcing him to work with his estranged father as they track down the culprit, who may be an accomplice of the town’s storied serial killer, The Whisper Man. TheRobert De Niro movieis being written by Ben Jacoby (The First Omen) and Chase Palmer (2017’sIt) and has director James Ashcroft (The Rule of Jenny Pen) attached.

PerDeadline,Adam Scott and Michelle Monaghan have joined the cast ofThe Whisper Man. So far, the characters that they will be playing are unknown, as is De Niro’s character. However, given their relative ages, it seems possible that Scott could play the man on the hunt for his missing son, while De Niro plays his father. However, Scott could be playing detective Pete Willis, who also has an important role in the story, while De Niro plays the imprisoned Whisper Man. Additionally, Monaghan may have been tapped to play Willis' fellow detective Amanda Beck.

Considering the fact thatThe Whisper Manwill be De Niro’s next project with Netflix after his hitpolitical seriesZero Day, if they play their cards right, the movie could become a huge success. Luckily,both incoming cast members have the right level of experienceto bring their characters to life in a compelling way. Monaghan has most recently been seen inThe White Lotusseason 3, but her resume includes an ample array of thrillers that includesGone Baby Gone,Eagle Eye,Source Code,True Detective, andPatriots Day.

Zero Day, which also features Lizzy Caplan, Jesse Plemons, Joan Allen, Connie Britton, Dan Stevens, Angela Bassett, and Matthew Modine, stars De Niro as a former president who is in charge of investigating a deadly cyberattack.

Although Adam Scott is likelybest known for his roles in comedies includingParks and RecreationandParty Down, he has dabbled in many other genres, especially since he appeared opposite Reese Witherspoon in the star-studded cast of the HBO dramaBig Little Lies. His recent appearances inThe MonkeyandGhostwriterhave likely prepared him well for the new movie, as has his role in theSeverancecast, leading the twisty Apple TV+ sci-fi thriller.

More Big Stars Could Fill Out The Cast

Because there are at least two major adult roles that are still unfilled inThe Whisper Man, it seems likely that more casting announcements will come soon. If the production can find more actors of the caliber of Monaghan, Scott, and De Niro, it will become a truly star-studded affair. However, even if less well-known actors fill the remaining roles,having this trio at the center of the new movie makes it a particularly intriguing titlefrom Netflix’s upcoming slate.
