Personally, I am not aware of any websites yet, perhaps others may know, but before there was ever a Rita Moreno there was famous Hollywood movie star Maria Montez, who was Dominican. A few years ago, the Dominican movie "Nueva Yol: Por Fin LLego Balbuena" was submitted to the Academy of Motion Pictures, Arts and Sciences (the folks that dish out the Oscars) for Best Foreign Film. It unfortunately didn't make it to the top 5 choices since hundreds of films are submitted every year.
