The title song, "Rosie", was composer 'Harry Warren''s final song contribution to a produced movie. The melody is actually a rework of a song, "Me And My Baby," with original lyrics by Sammy Cahn, that was written for, but not used in, the Jerry Lewis film Rock-a-Bye Baby (1958).
Remake of an earlier Universal property, Three Kids and a Queen (1935), starring May Robson and Charlotte Henry in the roles played here by Rosalind Russell and Sandra Dee.
The last of nine Ross Hunter productions to star Sandra Dee , being preceded by The Restless Years (1958), A Stranger in My Arms (1959), Imitation of Life (1959), Portrait in Black (1960), Tammy Tell Me True (1961), If a Man Answers (1962), Tammy and the Doctor (1963), and I'd Rather Be Rich (1964).
