Desc: Jean Ziegler, l'optimisme de la volonté: Directed by Nicolas Wadimoff. With Jean Ziegler, Erica Deuber-Ziegler, Roberto Fernández Retamar, Segis Petschen. In 1964, Jean Ziegler was asked by Che Guevara to fight the "capitalist Monster". Former collaborator of Kofi Annan, professor and writer, Ziegler's books still act as a manifesto to left-wing intelligentsia. At the UN Human Rights Council, he fights against "vulture funds", a new avatar of the "Monster". He goes back to Cuba, in his opinion the mother of all anticapitalist forces. The visit becomes a dialogue between reality and symbolism, confronting his thinking with today's Cuban destiny.
