The first foreign language feature made in America with live dialogue.
This is the Spanish-language version of Blaze o' Glory (1929), shot concurrently but released later.
The first in a trend of alternate foreign-language versions of films made by Hollywood studios, which lasted from 1929 through about 1932, when dubbing techniques were improved. Ironically, though the process was adapted by major studios like Universal and Paramount, this trend-starting film was produced by a minor company, Sono Art.
