Named after Max Ernst's painting of a ruined, melting landscape, this British documentary traces Dada and Surrealism from their shared root in the devastation of the First World War. It opens in Zurich's Cabaret Voltaire, where Hugo Ball and Tristan Tzara staged nonsense poetry and noise performance as a direct assault on the culture that had produced the trenches, then follows the movement's spread to Berlin, Cologne, and Paris. The film tracks how Dada's anger curdled into André Breton's more structured Surrealism, built on automatic writing and the imagery of dreams, with Max Ernst, Salvador Dalí, Man Ray, and Hans Arp as its central figures. Archival photographs, film clips, and paintings carry most of the argument, supported by narration that treats the two movements as a single continuous reaction to a world that had stopped making sense. It closes on the uneasy question of what became of that rebellion once its artists were absorbed into museums.
