Passage 2
When American-born actor Michael Pena was a year old, his parents weredeported. They had illegally walked across the U.S.border from Mexico and whenthey were caught by immigration authorities, they sent Pena and hisbrother to stay with relatives in the U.S.   \"It was quite abit of a gamble for my parents,\" says Pena,  \"but theycame back a year later.\" Pena′s father, who had been a farmer inMexico, got a job at a button factory in Chicago and, eventually, a green card.
Pena stayed in Chicago until, at 19, he fled to Los Angeles to pursue hisacting dreams.
This family history makes Pena′s latest role especially personal. In CesarChavez, Pena plays the labor leader as he struggles to organize immigrant California farm workersin the 1960s. To pressure growers to improve working conditions and wages,Chavez led a national boycott of table grapes that lasted from 1965 to1970 and is recorded in the film. Chavez, like Pena, was the American-bornson of Mexican farmers who immigrated to the U.S.   \"He understandsthis duality, the feeling of being born in a place but having a verybig idea of where your heritage comes from,\" says the film director,Diego Luna.  \"This thing of having to go to school and leam inEnglish and then go home to speak Spanish with your parents.\"
As immigration policy is hotly debated on Capitol Hill this year, Luna andothers who were involved with Cesar Chavez are hoping the movie will sparknew support for reform and inspire American Latinos to get involved.  \"The message Chavez left was that change couldn′thappen without the masses being a part of their own change,\" saysFerrera, a first generation Honduran American who plays the union leader′s wife Helen. Rosario Dawson, who co-founded the advocacy group VotoLatino, plays Chavez ally and labor leader Dolores Huerta.
Immigrant-rights issues in the U.S.have evolved substantially in the years since Chavez founded the UnitedFarm Workers (UFW). Undocumented workers now make up a far larger share ofthe agricultural workforce in Californiathan they did in the 1960s, according to Miriam Pawel,author of The Crusades ofCesar Chavez, published the next month. Chavez was vehemently againstillegal immigration, believing it made strikes difficult to execute andweakened the union. He initiated a program in the mid-1970s to locateundocumented farm workers and report them to immigration officials, Pawelwrites. And despite his early victories, Chavez′ s UFW unionrepresents just a small part of those working on California farms today.
\"Chavez′s legacy is not in the field, which is sad,\" says Pawel.Still, she says, his organizing strategies, featured extensively in CesarChavez, have been adopted by other activists, including those leading themodem immigrant-rights movement. Chavez′s most important contributionmay have been humanizing the Latino population for the American public.Farm laborers, many of whom barely spoke English, traveled across thecountry during the grape boycott, standing outside grocery stores topersuade housewives not to buy grapes and to spread the word about theirplight. \"They gave the boycott this very human face,\" saysPawel.
\"It was families talking to other families,\" says Luna. \"It′ s about the power we have just by being who weare.\"
What has made Pena′ s role as Chavez in the movie Cesar Chavez so distinctive?
