The sound design is the star in ‘undertone,’ a podcast thriller with too much dead air

Ian Tuason’s debut horror film, “undertone,” is a deeply personal and quietly unsettling movie made with a very small budget. Filmed in the house where Tuason cared for his parents before their deaths, the film uses the actual location as both a setting and a source of emotional weight. The house, filled with floral wallpaper and religious symbols, feels claustrophobic, and the camera stays entirely within its walls, mirroring the overwhelming pain, exhaustion, and grief experienced by the characters.
