What it does offer is an engrossing visual and aural experience. After their collaboration in Under the Skin, Glazer reteams with composer Mica Levi for a sparse, guttural score that makes the banal domesticity or administrative work into something otherworldly. I was pulled back to Mad God, Phil Tippett’s stop-motion journey into steampunk hell. That film was populated by desperate figures moving about in the shadow of giant biomechanical monsters whose vomit powered other monsters. Levi’s score, all bass growls and hums, is the sound of one of those monsters coming to life, like every time one of the Hess’s signed a document or scrubbed a window, they were giving some infernal being the power to take a step forward. When the score isn’t active, there’s a soundscape of Auschwitz going about its business. Pool parties are punctuated by gunshots, gardening is backed by staccato yells from guards. Special mention must be given to sound designer Johnnie Burn, who went as far as considering the distance from the homestead that certain functions in the camp took place and then incorporating that distance into what the family would’ve heard. Accompanying the sound of the film is the way that there’s always smoke in the distance, or the countless barracks of the camp that are just in the corner of the frame. Combined with the way that Glazer filmed his actors, with hidden cameras in the home as they went through a loose script, The Zone of Interest becomes immersive, voyeuristic, and justifies its ugly existence.
