"Lux Radio Theater" broadcast a 60 minute radio adaptation of the movie onDecember 29, 1947 with Frank Sinatra, Gene Kelly and Kathryn Grayson reprising their film roles.

For the most famous sequence in the film, Mickey Mouse was originally meant to be the dance partner of Gene Kelly. However, when Walt Disney refused to have his most famous character appear in an MGM film. Kelly turned to MGM's own animation studio and used Jerry Mouse of Tom and Jerry fame. William Hanna and Joseph Barbera, the writer/directors of MGM's "Tom and Jerry" cartoons, supervised the animation for the sequence.

The first pairing of three movies of musical stars Gene Kelly and Frank Sinatra.

This was the first film project for Pamela Britton.

When the dance sequence with Gene Kelly and Jerry the Mouse was screened for MGM executives, someone noticed that although Kelly's reflection shone on the floor during his dancing, Jerry's did not. This required Hanna, Barbera, and their team to go back in and draw Jerry's reflection on the floor as he was dancing.
