Famed designer Yves Saint Laurent provided the beautiful stylish wardrobe for Catherine Deneuve in the film. In a 2005 interview she said, "I think the clothes in Belle de Jour are very important to the style of the film because even today, when you look at it, it is still timeless."

In her private diaries that were published in 2005, Catherine Deneuve speaks of how Luis Buñuel wanted to use a crane shot in Belle de Jour but was unable to because no cranes were available in France at the time.

Buñuel's collaborator on the Belle de Jour screenplay (as well as many others), Jean-Claude Carrière helped Buñuel write his fascinating autobiography My Last Sigh, which was published in 1983. On the book's dedication page Buñuel says: "I'm not a writer, but my friend and colleague Jean-Claude Carrière is. An attentive listener and scrupulous recorder during our many long conversations, he helped me write this book."
