Dulac's first major success was "Âmes de fous" (1918), a serial melodrama written by Dulac herself. The film features an early appearance of actress Ève Francis, who introduced Dulac to her friend (later husband) Louis Delluc, filmmaker and critic. A short time later Dulac and Delluc collaborated on "La Fête espagnole" ("Spanish Fiesta", 1920), another film featuring Francis, which was proclaimed one of the decade's more influential films and allegedly a major French Impressionist Cinema work. However, only a few excerpts from the film exist today. Dulac and Delluc went on to collaborate on a number of pictures.
