西部劇, or "Western films," are a genre of movies that depict stories set in the American West during the late 19th to early 20th centuries. These films often feature cowboys, outlaws, and lawmen, showcasing themes of adventure, justice, and survival in a rugged landscape. The genre became popular in the early 20th century, with iconic figures like 约翰·韦恩 (John Wayne) becoming synonymous with Westerns. Classic elements include horseback riding, gunfights, and saloons, often set against vast, open landscapes. Westerns have influenced many other genres and continue to be a significant part of film history.
