A24 Debuts Trailer for Audio-Driven Horror 'Undertone,' Sets March 13 Theatrical Release

The trailer spotlights an audio-driven approach that propelled Ian Tuason from Fantasia breakout to a Paranormal Activity assignment.

Overview

  • Written and directed by first-time feature filmmaker Ian Tuason, Undertone follows a skeptical podcast host caring for her dying mother who receives 10 unsettling recordings that begin to unravel her reality.
  • Nina Kiri stars as the primary on-screen presence, with other characters heard only as voices, underscoring the film’s focus on sound design and what Tuason has described as a “found audio” concept.
  • A24 acquired worldwide rights after a six-buyer bidding war ignited at the film’s Fantasia premiere, with the deal closing in the mid-seven-figure range.
  • The film is slated for the Sundance Midnight section later this month after drawing early praise for its slow-burn, sound-driven scares.
  • A24 and multiple outlets list a U.S. theatrical release on Friday, March 13, 2026, though at least one report cites March 26.
