In a 1940 interview, Grable stated she was "sick and tired" of show business and that she was considering retirement. Soon thereafter, she was invited to go on a personal appearance tour, which she readily accepted. The tour brought Grable to the attention of Darryl F. Zanuck, the head of 20th Century-Fox, who offered her a long-term contract. "If that's not luck, I don't know what you'd call it", Grable said in her first interview after signing with the studio. Zanuck, who had been impressed by Grable's performance in "DuBarry Was a Lady", was, at the time, in the midst of casting the female lead in the musical film "Down Argentine Way" (1940). The role had originally been assigned to Alice Faye, Fox's most popular musical film star, but she had to decline the part due to an unspecified illness. After reviewing her screen test, Zanuck cast Grable as Faye's replacement in the movie. The film was a lavish Technicolor musical and co-starred Don Ameche and Carmen Miranda. Grable's performance of the song "Down Argentine Way" is considered a highlight of the film.
