Mario Lanza made two separate recordings from this film, both for RCA. The first, in mono, used the new lyrics especially written for the film, in addition to several songs written especially for the movie. The second, a stereo album released in 1959, featured soprano Norma Giusti as Kathie and, like the mono version, the new songs, in addition to some of the songs from the stage production. But the songs from the stage version were sung on this album with their original 1924 lyrics, not with the revisions heard in the film.
Average Shot Length (ASL) = 16 seconds .
Despite a request by producer Joe Pasternak, the mentor of her early film career at Universal, Deanna Durbin would not come out of retirement to play the role of Kathie the barmaid.
In August 1952 Mario Lanza recorded the soundtrack. The whole recording was done in single takes. Every phrase in it was Lanza magic at its best. However, on the film set things were not to go well at all. The first scene to be shot was the song "Beloved" on the terrace. Director Curtis Bernhardt did not like the way the song was sung and corrected Lanza, telling him that he was putting too much emotion in his singing instead of sounding more stuffy and rigid like a Prussian prince. Lanza informed Bernhardt that he was to direct only his acting, and that Lanza's singing was strictly Lanza's department. Bernhardt would not accept this, and Lanza would not be told how to sing by a movie director. The end result was that Lanza walked off the set and vowed not to return as long as Bernhardt was the director. The studio took an injunction against Lanza for damages and losses. He could not perform in public, on radio, or in the recording studio for the remaining time of his contract with MGM (which was then 15 months). A solution was reached in May 1953: the studio would remove the embargo on Lanza if he would allow his voice to be used while another actor played the part of the prince. This was agreed to and the filming got under way with Edmund Purdom lip-synching Lanz
