Pablo Cruz, producer of the biopic based on the beloved union activist César Chávez has spoken out regarding the allegations made against him that claimed the film engaged in non-union busting hiring practices.

According to Fox News Latino, Pablo Cruz of Canana Films, the Mexican production company who produced the film César Chávez: An American Hero, denied the recent claims made by critic Chamba Sanchez on Facebook that they "fired unionized workers and outsourced part or the entire production to Mexico."

Fresh off of the Berlin Film Festival, Cruz told Fox News Latino that the producers of the biopic used union workers, adding that no country in the world "would allow them to make a film that does not have union workers."

Mexican actor Diego Luna directed the biopic on the influential leader, which is co-produced by Academy award-nominated actor, John Malkovich and Mexican actor Gael García Bernal, among others. Michael Peña stars in the title role, Rosario Dawson stars as Dolores Huerta, who co-founded the National Farm Workers Association with Chávez, and America Ferrera plays César Chávez 's wife, Helen Chávez. The moving script, which includes passionate speeches and dialogue, was written by Keir Pearson, who wrote the Oscar-nominated screenplay for Hotel Rwanda.

In addition to denying the claims, Cruz reiterated that big stars in the film, such as the aforementioned actors and directors, Luna, Ferrera, Malkovich and Dawson, wouldn't have given the film the green light without having union actors and workers in the film. All actors were members of the SAG-AFTRA union or a Mexican labor union, he added.

"It was the most ridiculous (accusation)," Cruz told Fox News Latino. "Making up a story like that makes no sense."

It's also important to note that they were also forced to pay additional fees to the Mexican union for American actors who were part of the film, Cruz added.

What does Cruz have to say about the claim that the movie's production was outsourced to Mexico?

Cruz told Fox News Latino that his company, Canana, is a Mexican company, although it has an office in Los Angeles, Calif.

"It was normal for us to shoot in Mexico," he said, adding the finances for the film also came from Mexican investors. "It's always been a Mexican film."

The agriculturally-rich backdrop of the César Chávez biopic was in Sonora, Mexico for it "still looks like the 1960s California's San Joaquin Valley" where Chávez got his start. The grapes themselves also added to the landscape of the film and were in season during the actors' schedules.

Pantelion Films, the first major Latino-focused Hollywood studio launched in 2010 in partnership with Mexico's Grupo Televisa, is distributing the film in North America, Fox News Latino adds.
