In the late 1920s, Hollywood studios depended on the successful exportation of their films to other countries. While silent films could easily be sold to other countries, sound film could not. By 1928, the preferred approach to the foreign-language market was to develop more than one version of a film using the same script, sets and costumes of the English-language original, but employing different actors who could speak the languages such as French, Spanish or German. In an April 30 issue of the "Hollywood Filmograph", it was declared that Spanish-language films were "all the go and producers spending millions of dollars on them." In February 1930, Universal announced that Paul Kohner would supervise numerous foreign-language productions, including several shot in Spanish. By September 1930, Universal focused primarily on making Spanish-language versions of films for the potential market.
