Sam Shepard made a big entrance into the world of movie acting as the doomed romantic farmer in Terrence Malick's critically acclaimed "Days of Heaven." He has appeared in 40-odd films since that 1978 breakthrough. He has played iconic roles (heroic test pilot Chuck Yeager in "The Right Stuff"), walk-ons (Valerie Plame's father in "Fair Game") and a whole lot of sheriffs.
But rarely has he appeared to enjoy himself so thoroughly as in the new Bolivian Western, "Blackthorn." Shepard, 67, stars as an aging Butch Cassidy, who evaded an army ambush to live out his golden years as a solitary rancher.
