Underpass is located at the intersection of material deformations and the genre tropes of horrors and thrillers. The defining event of the second half of the 20th century – the assassination of John Fitzgerald Kennedy, is in the film combined with the creative decomposition of grainy 8mm film. The dread of the initial shock is conveyed by non-figurative scratches and omnipresent eye-like perforations. The internal rhythm was set to recording from a police dictabelt, which captured the global encounter with the real in a similarly unstable vein.
