Lukas Marxt’s fourth film about the Salton Sea in Southern California focuses on 1944/45, when about 150 dummies, replicas of the bombs of Hiroshima and Nagasaki, were dropped there for ballistic tests. “Marine Target” measures the remains of the wooden target platforms from up close and high above. The disconcerting soundtrack to this fascinating filmic study is provided by a swelling adaptation of the Nigerian hit “Atomic Bomb” by William Onyeabor.

For his monumental study of displacement, Nikolaus Geyrhalter has travelled across continents, mapping a new kind of landscape that has become detached from geographical or climatic conditions under palm trees, on mountains, at rivers, in the snow. Washed up, blown in, piled up, caught or left somewhere – where once the forces of nature were at work, garbage now dominates the shape of things. It has even brought forth a new social type: the relocator.

As in all his films, Nikolaus Geyrhalter operates the camera himself. It stands still, often for minutes, as if it couldn’t believe what presents itself: plastic webs seemingly grown together with the scrawny branches on embankments, decaying newspapers and cocoa powder packaging in the excavated soil of a potato field in Switzerland, beaches seamed at the waterline by a carpet of Styrofoam and plastic containers. In equally delicately composed images, the filmmaker focuses on the machines and people who work away at these garbage landscapes. They excavate and compact, collect and sort, sweep and rake, move one thing this way and the other that way with grapplers or hands. Well-formed and without comment, the inner workings of a self-sustaining system are revealed in which a process of alienation is underway that causes problem and solution to drift apart.
