Belle de Jour, directed by the renowned Spanish filmmaker Luis Buñuel, was released to audiences in Paris in 1967 and quickly became a classic of world cinema. The film stars Catherine Deneuve as Séverine Serizy, a young housewife who is trapped in a mundane marriage. Unfulfilled and yearning for a more thrilling life, Séverine begins working as a prostitute during the day while remaining a devoted wife at night. The narrative is infused with themes of eroticism, fantasy, and the stark contrasts between societal norms and individual desires. Buñuel employs surrealism to challenge viewers’ perceptions of reality and morality, turning the seemingly simple story into a complex exploration of the psyche and human sexuality.

Buñuel's film diverges from traditional narratives, embracing a non-linear storytelling approach that reflects Séverine's fractured identity. The dreamlike sequences, combined with the film's distinctive visual style—even in scenes depicting sexuality—allowed Buñuel to push boundaries related to portrayals of women in cinema. The film's title, Belle de Jour, translates to 'Beauty of the Day,' which serves as a dual reference to Séverine’s beauty and her daytime escapades. Upon its release, the film captured critical acclaim for its avant-garde approach and Deneuve's haunting performance, solidifying her status as a cinematic icon.

Belle de Jour has since become a seminal work in the canon of world cinema, influencing various filmmakers and spawning discussions on its provocative themes. Viewed through a contemporary lens, the film raises questions about women's autonomy, societal expectations, and the nature of desire itself. Buñuel's deft handling of such themes, through a lens of surrealism and dark humor, resonates with audiences well beyond its time, leaving an enduring legacy in cinematic history.
