A sprawling suburban home, an inviting new neighborhood and an anonymous letter threatening to spy on you indefinitely. What could go wrong? 

In a new trailer for The Watcher, the Brannock family excitedly move into their dream home in a seemingly quiet, safe, Stepfordlike suburban neighborhood. But that’s not quite the case here: They begin to receive ominous letters from a person calling themself “the Watcher,” who claims to be keeping a close eye on both the house and its new inhabitants. Set to a haunting rendition of Olivia Newton-John’s “Hopelessly Devoted to You,” sinister secrets from the neighborhood quickly come spilling out, and the Brannocks are constantly looking over their shoulders (often with bats in hand) waiting for “the Watcher” to strike.

“I will never stop watching,” he says.

Led by Naomi Watts and Bobby Cannavale, the series includes a majorly stacked cast. (We’re talking Mia Farrow, Noma Dumezweni, Joe Mantello, Richard Kind, Terry Kinney, Margo Martindale and Jennifer Coolidge, to name just a few.) The Watcher is also based on a true, as-yet-unsolved case about the real-life family who moved into 657 Boulevard in Westfield, New Jersey, and began receiving threatening letters from a stalker. 

Is it a prank? Is it a disgruntled new neighbor? With threats like “If you care about that family, you’re going to get out of that house” and “It might not frighten you yet, but it will,” you’ll probably agree with Coolidge’s realtor character when she says to “sell sell sell.” 

Presenter at Tudum 2022 and Never Have I Ever star Maitreyi Ramakrishnan spoke for all of us when she said: “So, that looks terrifying, and also, like, I’m going to be immediately obsessed.”
