MGM gave composer Miklós Rózsa only a week's notice to come up with a ballet for Moira Shearer. The composer said the assignment was beyond his range under the circumstances and was asked to provide an alternate piece. He selected Sergei Rachmaninoff's "Rhapsody on a Theme by Paganini".
The similarities between this film's second story ("Mademoiselle", featuring Ethel Barrymore, Leslie Caron, Farley Granger, and Ricky Nelson) and Tom Hanks' 1990s hit Big (1988) suggest that the writer of the latter may have been inspired by the former.
