The bright sun of the French Riviera is deceptive in this languorously alluring exercise in slow-burn suspense from thriller specialist Jacques Deray and legendary screenwriter Jean-Claude Carrière. Ten years after their breakup, one of European cinema’s most iconic real-life couples, Alain Delon and Romy Schneider, reunited for this film, bringing a palpable erotic chemistry to their performances as the bronzed and beautiful vacationers whose blissed-out summer holiday on the Côte d’Azur is interrupted by the arrival of an old acquaintance (Maurice Ronet) and his eighteen-year-old daughter (Jane Birkin)—unleashing a gathering tidal wave of sexual tension, jealousy, and sudden violence. A paragon of 1960s modernist cool thanks to effortlessly chic clothes and a loungy Michel Legrand score, La piscine dives deep to reveal sinister undercurrents roiling beneath its seductive surfaces.
