At first it seems like a contradiction, a historical irony: Jean-Louis Comolli – the editor of Cahiers du Cinéma during its period of Althusserian Marxism in the late 1960s and early 1970s, the author of some of the most important texts to critique the ideological nature of the “impression of reality” in the cinema (‘Cinéma/idéologie/critique,’ a manifesto-editorial co-signed with Jean Narboni, and the series of articles ‘Technique et idéologie’) – has gone onto become a prolific, highly regarded documentary filmmaker, with a filmography that stretches from the 1970s to the present day and includes more than fifty titles, made for both cinema and television. Is this transition from film theory to film practice a stunning volte-face, a theoretical apostasy from the revolutionary ethos of the post-1968 era, so common among other soixante-huitards? Nothing of the sort.
