->''"It is possibly the best-known erotic film of modern times, perhaps the best. That's because it understands eroticism from the inside-out--understands how it exists not in sweat and skin, but in the imagination."''
-->-- '''Creator/RogerEbert'''

'''''Belle de Jour''''' is one of the most famous films directed by [[Creator/LuisBunuel Luis Buńuel]]. Released in 1967, it starred then-débutante Catherine Deneuve.

Séverine (Deneuve) looks outwardly like the perfect {{Housewife}}. Beautiful, demure, well-mannered and impeccably groomed, she is the very image of bourgeois propriety. In fact she is a masochist who likes to fantasize about being humiliated and treated like a sex object. On the recommendation of a friend, she acts out on these fantasies by becoming a part-time prostitute in an upscale brothel. Since she only turns tricks during her husband's business hours, she is given the moniker Belle de Jour, "daytime beauty".
