Precarious Sociality, Ethics and Politics: French Documentary Cinema in the Early Twenty-First Century brings an original perspective on French cinema's 'return to work' in the early twenty-first century, focusing on the transformation of cinematic activism in view of the rapid dissolution of class narratives and solidarities. It is argued that, reckoning with widespread anxieties about job precarity, social uncertainty, loss and invisibility in French society, filmmakers catalysed new modes of intervention, best described as embodied praxes of sociality. Combining rigorous film analyses with concepts borrowed from philosophy, sociology, geography and political theory, this study positions documentary as a privileged point of articulation between aesthetics, politics and ethics. The wide-ranging film corpus features well-established auteurs (Agnes Varda, Raymond Depardon, Denis Gheerbrant) and less canonical filmmakers to celebrate the vitality of contemporary French documentary cinema and its creative contributions to international discussions about work, precarity and social resilience.
