Little Big Man (1970)

Hoffman plays 121-year-old Jack Crabb, a questionable hero, who claims in his time to have been captured by the Cheyenne, acquainted with Wild Bill Hickock, and the last survivor of the Battle of the Little Bighorn. The film’s anti-establishment position is notable both as a protest against the war in Vietnam and also as a show of sympathy towards Native Americans and their position in American history.
