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.
