A revisionist western set in turn-of-the-last-century Texas, The Ballad of Gregorio Cortez gives Edward James Olmos a career part in the title role, a Mexican-American farm worker who goes on the run after he’s slapped with an unfair murder charge, trailing six hundred Texas Rangers behind him. A low-key and low-budget frontier epic told with total life-marred historical veracity, Young’s film breathes life into a legendary episode of immigrant resistance to nativist bullying.
