Little Big Man is a 1970 American revisionist Western directed by Arthur Penn and based on the novel Little Big Man by Thomas Berger. It is a picaresque comedy about a white male child raised by the Cheyenne nation during the 19th century. The film is largely concerned with contrasting the lives of American pioneers and Native Americans throughout the progression of the boy's life. The movie stars Dustin Hoffman, Chief Dan George, Faye Dunaway, Martin Balsam, Jeff Corey and Richard Mulligan. It is considered a revisionist Western, with Native Americans receiving a more sympathetic treatment and the United States Cavalry depicted as villains. Despite its satirical approach, the film has tragic elements and a clear social conscience about prejudice and injustice. Little Big Man is considered an example of anti-establishment films of the period, protesting America's involvement in the Vietnam War by portraying the U.S. military negatively. In 2014, Little Big Man was deemed "culturally, historically, or aesthetically significant" by the Library of Congress and selected for preservation in the National Film Registry.
