Now time, Western firm is thought like an old style movie. Indian, craggy terrain like a desert and threaten looking men with the gun are symbol of the Western firm. Even if these firms are old style one, still many of people like this genre of movie because in here American can find there own culture and their spirit of reclamation. If we concentrate on landscape and characterization of hero in this genre, we can understand western culture easily. As you know, Western is very barrenness place population was exiguous. That makes lack of industry follows lack of sources. "These sources are constant temptations to live by violence because banded together, the people who have a enough power to grab up the wealth." Alike, as a primary of civilization, the citadel surrounded by native tribes, in the "same position in a firm about cowboys and Indians as the sheriff does in a lawless town." Also landscape is natural to the genre.
