From this initial collection of filmmakers with left-wing political agendas, Marker created the group S.L.O.N. (Société pour le lancement des oeuvres nouvelles, "Society for launching new works", but also the Russian word for "elephant"). SLON was a film collective whose objectives were to make films and to encourage industrial workers to create film collectives of their own. Its members included Valerie Mayoux, Jean-Claude Lerner, Alain Adair and John Tooker. Marker is usually credited as director or co-director of all of the films made by SLON.
