In June 2015, forty-five years after OUT 1 was made, the filmmakers went to Paris to interview cast and crew members and to revisit some of the film’s most significant locations. THE MYSTERIES OF PARIS features new contributions from actors Bulle Ogier, Michael Lonsdale and Hermine Karagheuz, cinematographer Pierre-William Glenn, assistant director Jean-François Stévenin and producer Stéphane Tchal Gadjieff, but also rare archival interviews with actors Jacques Doniol-Valcroze and Michel Delahaye and, most prominently, illuminating statements by director Jacques Rivette himself from two different archival interviews.

We follow 24 hours in the life of a being moving from life to life like a cold and solitary assassin moving from hit to hit. In each of these interwoven lives, the being possesses an entirely distinct identity: sometimes a man, sometimes a woman, sometimes youthful, sometimes old. By turns murderer, beggar, company chairman, monstrous creature, worker, family man.

Between 1931 and 1993, the main Renault plant occupied the whole of an island in a loop in the river Seine to the west of Paris. This was one of the most modern factories in Europe. It was also a bastion of trade-unionism, one of the major hotspots of the events of May and June 1968. Decugis’ film records a process of dismantlement, month-by-month, from April 2004 to March 2005. Demolition began at the downstream end, with the generating plant, then proceeded building by building. The camera remains on the opposite banks, filming the island from across the river. The narration pinpoints and expounds on what is being shown. By March 2005, ‘deconstruction’ is complete. Depollution lasts into 2006.

French independent director Paul Vecchiali playfully bites the hand that periodically feeds him (and many of the nation's other creative filmmakers) in this dark comedy. Writer and director Vecchiali stars as a moviemaker named Paul Vecchiali, who is trying to complete his latest project, a dramatic love story about a young couple whose relationship is complicated by the man's addiction to drugs. Short on funds, Vecchiali approaches the National Cinema Center, who offer loans and grants to independent filmmakers whom they believe are deserving. The NCC is less than impressed with Vecchiali's latest script, and they turn him down, just as they have done a number of times in the past. Angry and determined that the NCC will never break the spirit of another director, Vecchiali and his crew block out a plan to assassinate the nine members of the funding board, though the press and public seem more bemused than outraged by the sudden rash of killings.

A tribute to Mallarmé that not only asserts the continuing relevance of his work but also confronts its literary ambiguities with political and cinematic ambiguities of its own.
