This film, first titled La poubelle du labo (The Lab Trashcan), and after L'Enfer du cinéma (Cinema's Hell), has been projected for the very first time in September 1968 at the French Cinémathèque. It can be considered as the cinematographic equivalent of Tristan Tzara's method on how to make a dadaist poem by putting words in a bag, and it mostly rises from Isidore Isou's film enthusiasm. The film has been made in fact out of elements of film strips found in the trashcan of a film development laboratory, that have been subsequently taped together bit by bit following the exact order they were originally gathered.
