In Haruki Murakami's "Sputnik Sweetheart," the narrator reflects on a voice that resonates deeply within him, likening it to a moment from an old Jean-Luc Godard film. This comparison emphasizes the voice's ethereal quality, suggesting that it exists just outside the direct perception of his reality, much like a subtle cinematic detail that enhances the larger narrative. It conveys a sense of nostalgia and artistic beauty, invoking images of classic cinema that are rich in emotion and depth.

The metaphor underscores the profound impact that certain sounds or voices can have on one's psyche. The narrator is captivated by this voice, hinting at a connection to memories and feelings that linger in his awareness. Murakami's use of film imagery ties into the themes of longing and the search for meaning, revealing how art can influence our experiences and perceptions of love and desire.
