Prominent Mexican composer Silvestre Revueltas (who wrote the film's score) makes a brief appearance as a piano player in a bar. He places a sign over the piano which reads "Se suplica no tirarle al pianista" ("We beg you not to shoot at the piano player").
First Mexican super-production.
The opening exclamation point in Spanish is wrongly inverted in the title card: the correct form is "¡Vámonos con Pancho Villa!", not "!Vámonos con Pancho Villa!" The mistake can be checked in any copy of the movie.
