Sacheen Littlefeather says she paid a price when she decried Hollywood's stereotyped portrayal of Native Americans at the 1973 Oscars.
She says when she visited Brando after the ceremony, bullets were fired at his front door. No one was injured.
Littlefeather, who went on to appear in just a handful of films, also claims the U.S. government encouraged the entertainment industry to avoid hiring her as part of its effort to quash Native American activism.
She spoke Thursday during a presentation to TV critics on "Reel Injun: On the Trail of the Hollywood Indian," a documentary airing in November on the "Independent Lens" series.
