Why do we use a camera? Are we researching the social sphere as Robert Flaherty once suggested to Joris Ivens? In CINEMAFIA, Jean Rouch, Joris Ivens and Henri Storck talk about these matters. Other films that deal with these questions are Jean Rouch’s PAM KUSO KAR about rituals in Niger and PAS TOUT by Isabelle Prim and Ludovic Burel, a "family film" that takes place in an abandoned factory. From 1968 to 1970, the Medvedkin Groups used strategies to treat political experiences in a cine-matic manner. LES TROIS QUARTS DE LA VIE was shot by young employees at a Peugeot factory. They received support from Chris Marker and Bruno Muel. (Eléonore de Montesquiou)
