The French writer Georges Perec once collaborated with the director Bernard Queysanne to film his autobiographical novel Un homme qui dort (aka A man who sleeps) in 1976. This abstract, dreamlike black-and-white film, using the techniques of polyphonic cinema, reinterprets the novel's theme of avoidance or withdrawal from the world. The film's only character, a young man, inexplicably withdraws from society and goes about his life, eating and sleeping without saying a word, and almost mechanically walking back and forth. The character may be understood as representing a familiar “type” in traditional and modern literature, the “city stroller,” the “wandering Jew,” and above all Bartleby in Melville's famous short story. This essay will first briefly describe how the film substantially selects from the novel, then go on to analyze three aspects of his behavior (silence, eating and sleeping, pacing) and how they are closely linked to the rhythms of this film's distinctive “fascination” aesthetic and its musical rhythm. Meanwhile, this article will refer to the filmic ideas of Gilles Deleuze, Charles Baudelaire's poetry on modern life, and Giorgio Agamben's philosophical reflections on modern experience in order to enlighten us about this man who sleeps while living and walking in silence.
