Undertone trailer has sparked major buzz among horror fans after offering a haunting first look at what is already being described as one of the most unsettling films of the year. The upcoming A24 release is being billed as “the scariest movie you’ll ever hear,” leaning heavily into sound-driven terror rather than traditional visual scares.
In the film, a popular paranormal podcast host finds her life unraveling after receiving a series of disturbing audio recordings from an unknown source. As the messages grow darker, the recordings begin to follow her beyond the studio, blurring the line between investigation and obsession.
The Undertone trailer highlights a strong ensemble cast led by Nina Kiri and Adam DiMarco. They are joined by Michèle Duquet, Keana Lyn Bastidas, and Jeff Yung, all of whom appear prominently in the tense preview.
The film is written and directed by Ian Tuason, marking his feature-length directorial debut. Tuason has already been tapped to direct an upcoming installment in the Paranormal Activity franchise, a move that has increased anticipation around Undertone and its creative approach to psychological horror.
Undertone premiered on the festival circuit at the Fantasia International Film Festival in Canada during the summer of 2025, where it drew strong reactions from audiences. Following its debut, A24 acquired the distribution rights. The film was also showcased at the Sundance Film Festival, further boosting its profile ahead of a wide release.
The Undertone trailer places a clear emphasis on sound design, silence, and unseen threats, suggesting a horror experience that relies more on atmosphere and imagination than graphic imagery. Early reactions indicate the film could appeal strongly to fans of slow-burn, psychological storytelling.
Undertone is scheduled to arrive in theaters on Friday, March 13, positioning it as a major early-year horror release. With festival acclaim, a rising director, and a chilling premise, the Undertone trailer has already set high expectations among genre fans.
