Françoise Sagan was 17 when she scribbled out her first novel in the smoky jazz cellars of Paris’s Saint-Germain-des-Prés. The story was simple, maybe even familiar by today’s standards. Cécile, the willful teenage narrator, is vacationing on the Côte d’Azur with her rakish widowed father, Raymond. Two peas in a pod, they pursue an uncomplicated life of pleasure. Cécile sunbathes, swims, smokes, and sleeps with a handsome law student. When Raymond’s stuffy new girlfriend threatens to spoil her fun, Cécile plots to split them up, leading to tragic results. Published in 1954, Bonjour Tristesse was decadent, amoral, and scandalous. This 2024 remake, directed by the writer Durga Chew-Bose, stars Chloë Sevigny, Claes Bang, Lily McInerny, and Nailia Harzoune. —Elizabeth Winder
