French director best known for his romantic musical-comedy films.

Demy studied for two years at France's Technical School of Photography and Cinematography and then was an assistant to animator Paul Grimault (1952–54) and to director Georges Roquier (1954–57). Demy's early films include an adaptation of a Jean Cocteau playlet Le Bel indifférent (1957; The Indifferent Lover), and the full-length features Lola (1961) and La Baie des anges (1963; Bay of the Angels). In Les Parapluies de Cherbourg (1964; The Umbrellas of Cherbourg) all dialogue was sung to music by composer Michel Legrand; the film won the grand prize at the 1964 Cannes Film Festival.

Demy's Les Demoiselles de Rochefort (1967; The Young Girls of Rochefort) was modeled on the American musical On the Town and featured dancer Gene Kelly. His later films included such fanciful works as The Pied Piper of Hamelin (1972), L'Évènement le plus Important Depuis que l'Homme a marché sur la lune (1973; A Slightly Pregnant Man), Un Chambre en Ville (1982; A Room in Town), and his final musical Trois Places pour le 26 (1988; Three Places for the 26th).
