Robert Duvall
Robert Duvall is like fine wine. He only got better as he got older. Although many Western enthusiasts remember him for films like “True Grit,” “Joe Kidd,” and “Lawman,” he continued doing Western films in the 2000s, too. He starred in 2003’s “Open Range,” 2006’s “Broken Trail,” and in 2015’s “Wild Horses.” So essentially, he kept the cowboy tradition alive in both the 20th and the 21st century.
