As a preface to the French release of Aleksandr Medvedkin's satirical Happiness (1934), this documentary recounts the rise and fall of the Cine-Train which rolled for 294 days across the Soviet Union filming the problems and economic developments of the 1930s, incorporating meditative voiceovers, stock photographs and interviews with Medvedkin himself. The film opens and closes with a silent train in motion, and uses rich archival sources to reconstruct the utopian worldview of which nothing seems to remain. And yet, as Marker says, “the biggest mistake would be to believe that [the train of history] had come to a halt.”
