If you leave a door half open, soon you'll hear the whispers spoken. If your window’s left unlatched, you’ll hear him tapping at the glass. If you’re lonely, sad, and blue, the Whisper Man will come for you.

That’s the chilling playground rhyme at the center of The Whisper Man, a new thriller now streaming on Netflix. Starring Oscar winner Robert De Niro, Michelle Monaghan, and Adam Scott, the new film follows an investigation into a serial killer thought to have been imprisoned years ago. But when children start disappearing, the playground rhyme comes back to life — and the retired detective who first arrested the so-called Whisper Man is called back into action. 

Directed by James Ashcroft (The Rule of Jenny Pen, Coming Home in the Dark) and written by Ben Jacoby (The First Omen) and Chase Palmer (It), The Whisper Man is Netflix’s sixth partnership with the Russo brothers’ company AGBO. Adapted from Alex North’s novel of the same name, this is a chilling mystery and a family drama all wrapped into one.
