Zig-Zag, like Rivette's Paris s'en va from the following year, is based on the 'jeu de l'oie'. Ruiz's film is subtitled 'a didactic fiction about cartography'. Taking inspiration and materials from a map-related exhibition at the Centre Pompidou ("Cartes et Figures de la Terre"), Ruiz shows many maps and map-like figures. The film ends with the injunction: 'To know more, visit the exhibition.'
See here for the excellent analysis of spatial machinery in this film, at the site (e)space & fiction.
For a discussion of Ruiz illustrated with several maps, see Jonathan Rosenbaum's 'Mapping the Territory of Raúl Ruiz' here.
