Most Westerns from the 1960s to the present have revisionist themes. Many were made by emerging major filmmakers who saw the Western as an opportunity to expand their criticism of American society and values into a new genre. The 1952 Supreme Court holding in "Joseph Burstyn, Inc. v. Wilson", and later, the end of the Production Code in 1968 broadened what Westerns could portray and made the revisionist Western a more viable genre. Films in this category include Sam Peckinpah's "Ride the High Country" (1962) and "The Wild Bunch" (1969), Arthur Penn's "Little Big Man" (1970) and Robert Altman's "McCabe & Mrs. Miller" (1971).
