La telefonista della Casa Bianca

This was the last film appearance of Deanna Durbin. On August 22, 1948, two months after the picture wrapped, Universal-International announced a lawsuit brought against Miss Durbin for the sum of $87,083 in wages advanced to her. The actress settled the dispute by agreeing to stay on with the studio for an additional three pictures (including a project intended to be shot in Paris). Instead, Universal-International simply permitted Deanna's contract to expire on August 31, 1949. Upon leaving the studio after 13 years and 21 features, Deanna was paid $150,000 for the three abandoned films plus another $50,000 owed her for this movie. Miss Durbin then retired from all of show business. In subsequent years, producer Joe Pasternak, Deanna's early mentor at Universal, could not persuade Miss Durbin to resume her film career at MGM, and she would reject two prime female leads offered by the studio: in the Jack Cummings production of Cole Porter's Baciami kate! (1953), and in the Pasternak filming of Sigmund Romberg's Il principe studente (1954).
