This movie is basically for affectionados of Sam Pekinpah and Walon Green. The message of this film is that the nature of western life is underscored by the propensity of its people to live with recklessness and violence in generational terms. Think of it as sort of like, "The Wild Bunch" aftermath, about forty years beyond.
While the "Wild Bunch" was about the west during the period of industrialization around the turn of the century, "The Hi Lo Country" deals with the period of superindustrialization following World War II.
Woody Harrelson and Billy Crudup play two cowboys who fall for the same woman, Patricia Arquette. Harrelson as the violent "Big Boy" shows no sense of morality or humilty as the film's main protagonist, while Crudup as "Pete" is almost the exact opposite. Sam Elliot portrays a villanous rancher/industrialist, while the desirable Penelope Cruz is the overlooked, unrequitted love in Pete's life.
All of the actors turn in solid performances, but what makes this film special is the story itself, the direction, and Jerry Goldsmith's subtle, forceful soundtrack.
