When Ginger Rogers tells George Brent to be quiet because she is listening to the radio, to a number (instrumental) from a hit picture, the song is "Lovely to Look At" from Roberta (1935), in which she appeared with Fred Astaire in the same year.
Most critics agree that it is in this film that Ginger Rogers achieved solo movie stardom. Her studio, RKO, tried to insure this by not releasing any publicity stills of her with her buck-toothed, bespectacled, brunette persona.
In the scene where Carol dives into the lake, Ginger Rogers was extremely reluctant to do this because of the freezing temperature of the mountain water. The crew were actually putting their beer bottles into the lake to keep them cold. Despite her objections, the director made her jump in and swim under water. The bottoms of her two-piece swimsuit began to slowly slip down in doing so, but the camera was so far away it remained unseen.
Although an article in the November 3, 1934 edition of The Hollywood Reporter announced that Fred Astaire would be the lead in this film, RKO borrowed George Brent from Warner Bros. for this production.
When Emory goes to the general store, he sees a table full of magazines. Although the film magazines depicted are real publications --- Movie Mirror, Photoplay, The New Movie, Real Screen Fun, Screenland, Movies, etc. --- most covers appear to be fake, although Ginger Rogers would appear on most, several times, in the future. The exceptions are the June 1934 edition of Silver Screen with cover art of Rogers by John Rolston Clarke. He ignores his photos and picks out a copy of the August 1935 edition of Field & Stream with fish on the cover.
