Aside from a brief fetish for Latin Lovers in the silent era, roles for Hispanics and Latinos in American silent film were few, far between and generally quite minor. In the sound era, images of Hispanics and Latinos in Hollywood began to increase in number, although Latino characters were at first usually portrayed by non-Latinos in brownface whilst real Latinos were frequently used as all-purpose ethnic types.

1930s- In the first decade of sound, there weren't many roles for Hispanics or Latinos aside from in popular, long-running series like Zorro, The Cisco Kid and The Mexican Spitfire series, the latter a vehicle for Lupe Velez. Pedro Armendáriz mostly starred in Mexican films; when cast in American ones, he invariably had to exaggerate his accent sufficiently. Throughout the '30s and the following decade, Arizona-born Chris Pin-Martin appeared in almost eighty films, invariably as a heavily-accented, broken English-speaking Mexican in small roles and as sidekicks, like Pancho in the Cisco Kid movies and as Gordito in the Zorro series. The Zorro franchise, begun in the 20s, continued to be popular throughout the era. The Cisco Kid series dated back to the teens. In them, unlike with Zorro, Hispanic actors like Leo Carrillo, Duncan Ronaldo and Cesar Romero were usually cast in the lead. Hispanic actress Rita Hayworth (born Margarita Cansino) was initially billed as Rita Cansino in a series of unrelated B-movies. In them, she usually played a variation on the fiery Mexican maiden in need of an honorable Anglo's protection and love.

     Like other minorities in Hollywood (e.g. Asians, blacks, gays, Natives and women, to name a few), Hispanics and Latinos in the silent film era were almost exclusively produced by people who had little or no first hand experience of their subjects. But whilst Latinos may've been almost entirely excluded from the filmmaking process, a handful of actors found work in front of the camera and in the process opened doors for the generations that followed.
     In film's first decade, a few Latinos in fact were involved in American filmmaking. Before the Hollywood era, the filmmaking process wasn't centralized and films were shot around the country by wealthy entrepreneurs, a few of which were Hispanic. However, most American films in the 1890s were under ten minutes long and tended to focus on single actions like sneezing, laughing or opening a door.

Hispanic Heritage Month

September 15th to October 15th is officially recognized as Hispanic Heritage Month in the USA.The dates of the observance were chosen due to the timing of El Grito, the "cry" that brought the independence of Costa Rica, El Salvador, Guatemala, Honduras and Nicaragua's independence (followed closely by Mexico and Chile.).

"Hispanic" vs. "Latino"

I suppose it's kind of interesting that whoever named the month chose the term "Hispanic" instead of, say, "Latino." Hispanic sounds old-fashioned to me, but then again, I know people younger than me who refer to themselves as just that. I still think it's like calling February "Colored History Month" or May being "Oriental Heritage month." The government's choice of "Hispanic" probably owes to the fact that the term "Latino" was in less common usage forty years ago when the observance was instigated by Lyndon B. Johnson (initially as Hispanic Heritage Week). Both terms are considered offensive by some indigenists since they disappropriate Native Americans from their origins and languages by defining people with sometimes no European ancestry with Eurocentric terms.
