A24 is gearing up to release its latest horror sensation, Undertone, which is already being hailed by critics as the scariest movie you'll ever hear. Directed by Ian Tuason, the film is scheduled to hit theaters nationwide on March 13, 2026. After making waves at both the Sundance Film Festival and the Fantasia International Film Festival, the project has established itself as a must-watch for fans of elevated horror.

The story follows a paranormal podcast host who finds herself trapped in a living nightmare while caring for her dying mother. As she balances her domestic duties with her professional work, she begins to discover unsettling audio recordings that suggest she is not alone. The film relies heavily on innovative sound design to deliver its scares, moving away from traditional visual jumpscares to create a more immersive, psychological brand of terror.

Early reviews from outlets like Screen Rant and Dread Central have praised Tuason’s ability to turn everyday audio into a source of dread. By centering the narrative on the world of podcasting, Undertone taps into modern digital anxieties while maintaining a deeply personal emotional core. Horror fans can experience the sonic haunting for themselves when the film makes its wide debut later this month.
