This is a combination of Francis Ford Coppola's THE CONVERSATION, starring Gene Hackman, and the Alan Pakula's atmosphere, for instance PARALLAX VIEW, with a sort of Kafka like complicated story, where a simple dude, played by François Cluzet - the French Dustin Hoffman -, a simple office clerk, despaired and alcoholic, loses his job before being hired by a mysterious organization for listening recorded tapes, of conversations...In that purpose, our lead sits all day in an empty office, empty room. But everything will get awry for our lead will also have to deal with the DGSI - the French Intelligence Service, the equivalent of the US Homeland or British MI 5. Very impressive piece of work, but unfortunately spoiled by a wasted ending, a Hollywood like ending. So shame, for this reason I will never see it again.
