Liebesnächte in Sevilla (1948) was publicized as a dramatic adaptation of the novella Carmen by Prosper Mérimée in La revue des deux mondes (Paris, 15 Oct 1845) and is otherwise unrelated to Georges Bizet's opera Carmen. It is a remake of the film Die Liebe vom Zigeuner stammt (1927), which was directed by Raoul Walsh and stars Dolores Del Río.
Prosper Mérimée's famous story was first proposed as a vehicle for Rita Hayworth by her then husband, Orson Welles. He planned to write and direct a version based directly on the novel rather than the better-known opera version. However, his idea was turned down by Columbia boss Harry Cohn - who, nonetheless, revived the idea for Hayworth almost as soon as she and Welles broke up (They were divorced in 1947).
Alexander Korda was planning a version of "Carmen" to star Paulette Goddard, but in view of this production he canceled the project.
Glenn Ford's son reveals in the book about his father that, after the shooting was completed, Rita Hayworth discovered she was pregnant by him and went to the American Hospital of Paris in Neuilly-sur-Seine to get an abortion. Ford learned about this much later.
