‘undertone,’ from E1

- 

NINA KIRI plays a podcaster who lives with her dying mother in “undertone.”

(DUSTON RABIN A24)

With a red-faced ghoul who hypnotizes victims into cutting off their ears. The latter may be Tuason seeding his idea for a sequel.

Here the central story is that Justin, who lives in London, has received an email with 10 audio files recorded by a couple named Mike and Jessa (Jeff Yung and Keana Lyn Bastidas) who are trying to understand what she’s saying in her sleep. The sender is unknown. (Possibly an evil spirit hoping for the exposure of a mattress ad?) Justin, the believer, is instantly alarmed by how these eerie tapes escalate from cute banter to ghostly crying babies and backward incantations. Evy is the skeptic who dismisses the noises as either an online hoax or bad plumbing.

Due to the time zone differential, Evy and Justin record their show just before he heads out to work in the morning, which for her is 3 a.m. Most of the movie takes place in that witching-hour window, an airlessly silent time where an at-home pod-caster doesn’t worry about being interrupted by a leaf blower, an ice cream truck or a dog. Sound-designed by David Gertsman, “undertone” is so quiet that a tea kettle sounds like a fire alarm. Story-wise, it’s equally inert. One of the biggest action shots in the first hour comes when—eek! —a sink turns on.
