Chavez arrive at the North American premiere of "Cesar Chavez" during the SXSW Film Festival, in Austin, Texas. For Chavez, one of Cesar Chavez’s eight children and head of the Cesar Chavez Foundation, the screening for farm workers in Delano, Calif., was the most significant. “To come back where the work began, where so much history happened, then to be with people that work on a daily basis to put food on our table, it’s heartwarming," he said.
