Ein Mann der schläft

Yes, a film adaptation titled "Un homme qui dort" was released in 1974, directed by Bernard Queysanne and Georges Perec himself. The film is known for its faithful, almost literal, translation of the novel's introspective and observational style to the screen.

This novel is a significant early work by Perec, showcasing his characteristic experimental approach to narrative and his deep interest in the mundane and the overlooked aspects of urban life. It shares thematic connections with his later, more famous works like "La Vie mode d'emploi" through its meticulous observation and exploration of individual existence within a larger, indifferent world.

The novel is written in the second person, directly addressing the protagonist as "you," which creates an immersive and introspective experience for the reader. This unique narrative choice emphasizes the protagonist's detachment and the reader's role as an observer of his internal state.
