What is Undertone about?

Undertone follows the host of an “all-things-creepy” paranormal podcast who moves into her dying mother’s house to care for her, just as she starts receiving a series of disturbing audio recordings from a pregnant couple tormented by strange noises. As she listens, she realizes the woman’s story eerily mirrors her own, and each new recording pushes her further toward a fate she may not escape.

Key story elements:

  • A paranormal podcast as the central frame.
  • Ten mysterious audio recordings that drive the plot.
  • A focus on sound design over jump scares and big spectacle.
  • A psychological descent as reality and recorded sound blur.

Many early write‑ups describe it as “the scariest movie you’ll ever hear,” emphasizing headphones-level audio tension over gore.

Cast, director, and who’s behind it

Undertone is the feature debut of writer‑director Ian Tuason, expanding on his reputation for sound‑driven horror storytelling.

Main cast highlights:

  • Nina Kiri as Evy/Evy/Eevee (the podcast host and central character).
  • Adam DiMarco as Justin, her believer co‑host on the podcast.
  • Michèle Duquet as the ailing mother.
  • Keana Lyn, Jeff Yung, Kris Holden‑Ried and others in supporting roles.

A24 acquired worldwide rights after the film’s strong festival reception, positioning it alongside their other prestige horror titles.

Release history and festival buzz

Before its wide release, Undertone made a quiet but notable splash on the festival circuit.

  • Festival premiere: Fantasia International Film Festival, July 27, 2025.
  • Awards: Won the gold Audience Award for Canadian films at Fantasia, signaling strong word of mouth among genre fans.
  • After Fantasia, A24 reportedly secured worldwide rights in a seven‑figure deal, which helped fast‑track its 2026 theatrical rollout.

This path—from buzzy festival horror to wider A24 release—matches how several recent cult horror hits have broken out.
