The novel was a bestseller and won the 1985 Pulitzer Prize for Fiction. In 1989, it was adapted as a TV miniseries starring Tommy Lee Jones and Robert Duvall, which won both critical and popular acclaim. McMurtry went on to write a sequel, Streets of Laredo (1993), and two prequels, Dead Man's Walk (1995) and Comanche Moon (1997), all of which were also adapted as TV series.
