A24’s ‘undertone’ Sets HBO Max Streaming Date

One of the first horror hits of the year was A24’s unnerving undertone, which follows a podcast host caring for her dying mother.

Now, you can experience the film when it joins HBO Max’s streaming service on June 26th, 2026.

We attended the film’s World Premiere at last July’s Fantasia Film Festival, where Mary Beth McAndrews wrote: “Thanks to incredible sound design and a stellar lead, undertone is a deeply unsettling horror experience that treads familiar ground but still manages to surprise you.”

The film from Slaterverse Pictures and Black Fawn Films marks the feature film debut of writer/director Ian Tuason and stars Nina Kiri (The Handmaid’s Tale, Michèle Duquet (The Virgin Suicides), and Kris Holden-Ried (The Umbrella Academy). It has been so well-regarded that Blumhouse has tapped Tuason to direct the next Paranormal Activity and has been in discussions for several other major projects.

But first, undertone, a gets-under-your-skin chiller that’s built heavily on sound design and delivers a few solid punches.

undertone follows the host of an ‘all-things-creepy’ podcast who moves into her dying mother’s house to become her primary caregiver. When her podcast is sent 10 strange audio recordings of a young pregnant couple experiencing paranormal noises, she realizes the woman’s story mirrors her own as each new recording scratches at her sanity, drawing her into a fate she cannot escape.
