Purple Noon (French: Plein soleil; Italian: Delitto in pieno sole; also known as Full Sun, Blazing Sun, Lust for Evil, and Talented Mr. Ripley) is a 1960 crime thriller film starring Alain Delon in his first major film, along with Maurice Ronet (as Philippe Greenleaf) and Marie Laforêt (as Marge).

Directed by René Clément, the French/Italian international co-production is loosely based on the 1955 novel The Talented Mr. Ripley by Patricia Highsmith. The film, principally in French, contains brief sequences in Italian and English.

Billy Kearns (an expatriate American actor well-liked in France) plays Greenleaf's friend Freddy Miles, and Romy Schneider appears briefly in an uncredited role as Freddie Miles' companion.

Highsmith's source novel was adapted again in 1999 under the original title, The Talented Mr. Ripley.
