"Fiesta" (originally called "Fiesta Brava") starred Williams as Ricardo Montalbán's twin sister, Maria, who pretends to be her bullfighting brother in hopes of luring him back home. Audiences, and Williams, thought the film was silly, as Williams and Montalbán had vastly different accents. Montalbán was born in Mexico and was a native Spanish speaker while Williams had a mid-western accent picked up from her Kansas-born parents. Production was difficult with a multitude of problems. By 1947, Gage and Williams were married. Gage had traveled to Mexico for the making of the film. He got into a fight with an employee of the cast's hotel, was arrested, and subsequently thrown out of the country.The director of photography, Sidney Wagner, and one other crew member died of cholera from eating contaminated street food. Many of the film's stuntmen were sent to the hospital after being gored by bulls. Director Dick Thorpe hadn't wanted the bulls killed (as they usually were at the end of a bullfight) because he believed them to be too expensive to replace.
