Ulrike Ottinger settles her restless aperture on Vienna's Prater amusement park in this odd, engaging film. With a cast that includes the descendants of the "man without a torso," an illusion-machine repairman, and current and past park guests, Ottinger journeys back in time in an exploration of the attraction's cultural importance. She brackets her reminiscences with archival footage and a reworking of Alice in Wonderland as a hopscotch adventure; it's as jubilant and jarring as the Prater's own carnival amusements.
