That Midnight Kiss is a 1949 Technicolor American musical romance film also starring Mario Lanza (in his first leading role) and Kathryn Grayson.

Among the supporting cast were Ethel Barrymore, conductor/pianist Jose Iturbi (playing himself), Keenan Wynn, J. Carrol Naish, and Jules Munshin.

They hire the also famous tenor Guido Russino Betelli (Thomas Gomez), but Prudence does not feel comfortable with him on the stage.

Prudence happens to see an American-Italian truck driver, Johnny Donnetti (Mario Lanza), singing opera.

She soon becomes instrumental in bringing Johnny to public attention by insisting that he replace the opera troupe's defecting star tenor.
