Un peu de soleil dans l'eau froide, internationally released as A Few Hours of Sunlight and A Little Sun in Cold Water, is a 1971 French film directed Jacques Deray adapted from the novel of Françoise Sagan.

In Limoges, Nathalie Silvener, a married woman falls for Gilles, a depressed and brilliant Parisian journalist, himself in a relationship with a model.

[2] Le Nouvel Observateur referred to it as "un petit film démodé comme le petit roman de Sagan" (i.e., "a little film which is old-fashioned in the same way the little novel by Sagan is").

[3] Time Out was very critical, calling it "fatuous" and saying "Porel gives one of the most boring, suburban, asexual performances imaginable".

BSCNews calls it "a superb novel", praising Sagan's "simple and poetic" style.
