Joy of Man's Desiring
Que ta joie demeure is not a documentary about being a slave to the machine, alienation, dehumanisation or exploitation. Sound and image, editing and dramatic structure are merely employed to transpose workshops and factory floors into the cinematic space so as to explore the bizarre environments that workers adapt to and with which they skillfully interact, as if humanity had never done anything else since time immemorial.
