The film is obsessively visual about food. The orphans eat watery slop; the wealthy luchador, Ramses, eats a golden steak. Ignacio’s famous chant— "Get that corn out of my face!" —is not just a bizarre non-sequitur, but a proletarian rebellion against nutritional gaslighting. The narrative arc is literally driven by the desire for "eagle powers" (protein) versus "turtle powers" (beans).

Upon release, Nacho Libre received mixed reviews, with critics dismissing its slow pacing and repetitive jokes. However, it has since become a cult classic, particularly within Mexican and Mexican-American communities. While some argue it indulges in stereotypes (the "magical peasant," broken English), others defend it as an affectionate homage. The film treats its characters with dignity; the joke is never that Ignacio is a priest who wrestles, but that he is a terrible wrestler who is also a very good priest.

Ignacio (Jack Black) is a meek cook at the Oaxacan Monastery of the Poor Saviors. He secretly dreams of becoming a luchador (wrestler) to win money for the orphaned children he serves. After a failed attempt to buy the children protein-rich food, he teams up with a scrawny thief, Esqueleto (Héctor Jiménez). The duo wrestles as masked "tecnicos" (heroes), losing spectacularly before finding unorthodox success. The narrative follows Ignacio’s struggle to reconcile his religious vows with his violent, flamboyant alter-ego, culminating in a final match where he sacrifices his mask (and his dignity) to save the orphanage.
