Mes petites amoureuses (France/1974) - A 
I supposed so! Have you seen more by Eustache? 

Last Film I watched was " La Violenza: Quinto potere " (1972), a striking court drama with a marvellous Enrico Maria Salerno in the leading role as a Prosecutor (and, obviously, the only incorrupt member of the court) who tries to reveal the enormous political influences of the mafia within the process against a poor man who was blackmailed to murder a politician. Obviously a follow-up to Damiano Damiani's similar, successful films, this one hasn't got the same impact but it is very intense and interesting nevertheless (there are many authentic facts used) and, of course, it's carried by an excellent cast including Mario Adorf as a renowned investor (and Mafia Boss), Gastone Moschin as a corrup lawyer, Guido Leontini as the prosecuted Crook and Georges Wilson (and also a minimalistic score by Ennio Morricone).
