"Lux Radio Theater" broadcast a 60 minute radio adaptation of the movie on
October 20, 1941 with Tyrone Power reprising his film role.
Hedy Lamarr was the first actress approached to play Doña Sol, but MGM refused to loan her to Fox.
Rita Hayworth's first Technicolor film.
Among the actresses considered to play Doña Sol were Gene Tierney, Betty Grable, Jane Russell, Dorothy Lamour and Maria Montez.
By ancient tradition, the "traje de luces" can be of any color - although yellow is widely considered unlucky and rare - but the stockings must be pink. When Tyrone Power is wearing his white suit, his stockings are white - probably a costumer's decision.
Director Rouben Mamoulian based many of the film's color schemes and designs on the works of great Spanish painters such as El Greco and Velasquez.
In order to prepare for the role of Juan Gallardo, Tyrone Power attended a bullfight with his wife, Annabella. Because of Power's great stature as a star, he and his wife were given VIP seats in the center front of the ring. Power became violently ill witnessing the bullfight, and in order to get him out of the arena, Annabella said she was ill.
The tailor, Jose Dolores Perez, made exact copies of two of the matador suits of famed bullfighter Francisco Gómez Delgado (Armallita) to be worn by Tyrone Power.
