The Train Rolls On(1971)

Original title: Le Train en marche

This half-hour documentary by Chris Marker explores Aleksandr Medvedkin’s 1930s “Cine-Train,” a mobile film studio equipped with cameras, editing rooms, animation stations, and a laboratory. Traveling across the Soviet countryside, the train’s crew documented agricultural and industrial life—from Ukrainian harvests to southern steelworks—while living and working in cramped shared quarters.
