For decades in America, the most popular movie genre was the Western. Audiences loved gun-slinging sheriffs, dashing outlaws, thundering cattle drives, horseback pursuits, and majestic landscapes. More Westerns were produced in the 1950s than all other movie genres combined, but while they have attracted smaller crowds since then, they still have a persistent appeal. Early Westerns set the standard with cowboys played by the likes of Gary Cooper and John Wayne, and spaghetti Westerns, products of the Italian film industry in the ’60s and ’70s, starred box-office draws like Henry Fonda and Clint Eastwood. More recent Westerns have been romantic and thoughtful like Butch Cassidy and the Sundance Kid , Dances With Wolves , and Brokeback Mountain .
