The title is the same of a song popularized by the legendary Pedro Infante.
All the main actors (and even the director) worked with the legendary Pedro Infante at least once.
This movie was originally intented for Pedro Infante, who died before the production began. The title (of his most popular song) is an homage to him. Fernando Casanova, a good Onfante's friend, took the role instead.
Celia Cruz (the legendary queen of the Salsa) has a cameo as a singer.
