Acclaimed actor, musician and visual artist Wim Opbrouck and director Frederik Carbon take us on a surreal voyage on the Belgian North Sea. Like They Walk On The Moon is an expedition and concert movie, an inner exploration and artistic experiment. After many adventures, the makers ultimately try to perform the Poco Adagio from Saint-Saëns' organ symphony with the Brussels Philharmonic on a sandbank which emerges biannually for about one hour. Perhaps like humanity itself, emerging from the ocean to play its tunes for a brief period before sinking away again into the primordial ooze.
