With classic patrician features and an independent, non-conformist personality, Capucine began her film debut in 1949 at the age of 21 with an appearance in the film Rendez-vous de juillet (1949). She attended school in France and received a BA degree in foreign languages. Married for six months in her early twenties, she never remarried. In 1957, she was discovered by director Charles K. Feldman while working as a high-fashion model for Givenchy in Paris and was brought to Hollywood to study acting under Gregory Ratoff. She was put under contract by Columbia studios in 1958 and had her first leading part in the movie Sonsuz şarkı (1960). She made six more major movies in the early to mid 1960s, two of which (Aslan pençesi (1962) and Şafak sökerken (1964)) starred William Holden, with whom she had a two-year affair. Moving from Hollywood to a penthouse apartment in Lausanne, Switzerland, in 1962, she continued making movies, mostly in Europe, until her suicide in 1990.
