Mylène Demongeot (born Marie-Hélène Demongeot) is a French film, television and theatre actress and author with a career spanning almost seven decades and more than 100 credits in French, Italian and English speaking productions. She is most commercially known as Milady de Winter in The Three Musketeers (1961). She also has a cult following based on the Fantomas trilogy, as Hélène Gurn opposite Louis de Funès and Jean Marais: Fantômas (1964), Fantômas Unleashed (1965) and Fantômas Against Scotland Yard (1967). In the United States, she co-starred with David Niven in Otto Preminger's Bonjour Tristesse (1958) and in the United Kingdom she appeared in several comedies, including It's A Wonderful World (1956) and Upstairs and Downstairs (1959). A "veteran of cinema" who started as one of the blond sex symbols of the 1950s and 1960s, she managed to avoid typecasting by exploring many film genres including thrillers, westerns, comedies, swashbucklers, period films and even pepla, such as Romulus and the Sabines (1961) and Gold for the Caesars (1963). She was nominated for the BAFTA Award for Most Promising Newcomer to Leading Film Roles for her portrayal of Abigail Williams in The Crucible (1957) which also garnered her best actress at the Karlovy Vary International Film Festival, and was twice nominated for Best Supporting Actress at the César Awards for 36 Quai des Orfèvres (2004) and French California (2006). In 2017, she was made Knight of the Légion d'Honneur by ethologist and neurologist Boris Cyrulnik and Commander of the Ordre des Arts et de Lettres in 2007 under the French Republic.
