"Lux Radio Theater" broadcast a 60 minute radio adaptation of the movie on
December 26, 1949 with Jack Carson reprising his film role.
A poster for this movie can be seen on the wall of a dressing-room in Zack Snyder's 2011 movie, "Sucker Punch."
After nearly 10 years, Harry Warren, on loan from MGM, returned to write new songs for a Warner Bros. musical.(Ralph Blane was the lyricist.) For old time's sake, the score interpolated three Harry Warren standards for Doris Day to sing: "Nagasaki," lyrics by Mort Dixon; "I'll String Along with You," original lyrics by Al Dubin, "lullaby" lyrics by Ralph Blane; and "You Must Have Been a Beautiful Baby," lyrics by Johnny Mercer. This film was a remake of Twenty Million Sweethearts, which had featured, among the tunes by Warren and Dubin, "I'll String Along with You," sung first as a Dick Powell solo, then as a duet by Mr. Powell and Ginger Rogers. For her disc on Columbia Records, Doris Day teamed with Buddy Clark to croon "I'll String Along with You."
Obviously the star of her feature-film debut, Romance on the High Seas, Doris Day received only fourth billing, under Jack Carson, Janis Paige and Don DeFore. In this following vehicle, Miss Day's billing rose to the second spot, right below Mr. Carson.
The novelty song "I Tick, Tick, Tick" that Doris Day's character sings for her first audition was written to take advantage of the publicity surrounding the atomic clock which had just been invented. This clock, now even more precise, is now the standard to which all clocks in the US are set.
The scenes in this film featuring Doris Day and her young on-screen son had a special emotional resonance for Day, since in real life she had often had to leave her own pre-school-aged son Terry behind with his grandmother while touring as a big band singer in the 1940s.
