'Undertone' Trailer Gives Sneak Peek of the 'Scariest Movie You'll Ever Hear'

The upcoming horror movie Undertone is being called one of the best horror movies you’ll see this year… and the “scariest movie you’ll ever hear.”

In the new A24 film, the host of a popular paranormal podcast becomes haunted by terrifying recordings mysteriously sent her way.

The Handmaid’s Tale actress Nina Kiri and The White Lotus actor Adam DiMarco lead the cast alongside Michèle Duquet, Keana Lyn Bastidas, and Jeff Yung.

The movie was written and directed by Ian Tuason, who has been hired as the director of the upcoming Paranormal Activity project. Undertone is his feature film directorial debut and it was recently shown at the Sundance Film Festival. A24 acquired the rights after it premiered at Canada’s Fantasia International Film Festival in summer 2025.

Undertone will be released in theaters on Friday, March 13. Watch the trailer below.
