The Singer from Mexico (French: Le Chanteur de Mexico) is a French-Spanish musical film directed by Richard Pottier starring Luis Mariano and Bourvil, released in 1957. It was a screen version of Francis Lopez's operetta that premiered at the Théâtre du Châtelet on 15 December 1951. It was in a tradition of operetta films that stretched back to the early sound era.
It was shot at the Billancourt Studios and on location in Paris and Spain. The film's sets were designed by the art directors Sigfrido Burmann and Serge Piménoff.
Soundtrack.
"Francis Lopez composed for "Le Chanteur de Mexico" one of his best scores in which the arias integrate well into the atmosphere of the action; the airs were rapidly on everybody's lips: "Mexico", "Rossignol", "Acapulco", "Il est un coin de France", "Maïtechu", "Quant on voit Paris d'en haut", "Quant on est deux amis"." 
The operetta was revived in 2006 at the Théâtre du Châtelet with a cast that included Ismaël Jordi, Rossy de Palma, Jean Benguigui and Clotilde Courau.
