Diego LunaThree days before the movie’s national release, an audience of about 1,000 farm workers is seeing Diego Luna‘s biopic about the legendary civil rights leader and union organizer at the site where their union began in the 1960s. Cesar Chavez is getting an outdoor screening tonight at the Forty Acres outside Delano, CA, which is depicted in the film and now is a National Historic Landmark. Luna introduced the movie, which stars Michael Pena as Cesar Chavez alongside America Ferrera — who is at the screening — Rosario Dawson, Gabriel Mann and John Malkovich. The film scripted by Keir Pearson and Timothy J. Sexton won an Audience Award at SXSW this month after premiering at Berlin. It also screened at the White House last week. Lionsgate is releasing the pic from Pantelion, Participant Media, Televisa Cine and Image Nation. Participant is advocating for a national day of service on Cesar Chavez Day, March 31, which is a state holiday in California, Texas and Colorado. Here’s how the scene looked tonight:
