François Truffaut directed Confidentially Yours (French: “Vivement dimanche!”) a comedy mystery film noir, that would become his final work; he died of brain tumor in 1984, age 52.
Based on the 1962 novel The Long Saturday Night by American author Charles Williams, it tells the story of Julien Vercel (Jean-Louis Trintignant), an estate agent who is suspected of murdering his wife and her lover.
As Vercel is hidden in his office, his secretary Barbara Becker (Fanny Ardant) investigates these suspicious murders.
It was the last film directed by Truffaut before his death in October of the following year (of brain tumor).
Several critics pointed out that the film was both lighthearted and lightweight, and more impressive in style than in narrative and substance.
The film had a total of 1,176,425 admissions in France and was that year’s 39th highest-grossing film.
