Fight for freedom on U.S. farms documented by Food Chains movie

Do you care about who grows your food - and in what conditions these farm laborers work?

A new movie called Food Chains releases in the U.S. on Friday.

The documentary, produced by actress Eva Longoria and narrated by Oscar winner Forest Whitaker, examines working conditions for laborers harvesting tomatoes in Immokalee, Florida, and grapes in California's wine region Napa Valley.

It follows the fight of some laborers taking on big business interests to establish their rights.

The film premiered at the Berlin Film Festival and recently played at the Napa Valley Film Festival, and by the reaction in the Napa Valley Register, certainly prompted strong debate.
