Stone's film, "Guerrilla: The Taking of Patty Hearst," doesn't focus solely on the infamous Feb. 4, 1974, kidnapping of the newspaper heiress by the SLA. The first feature-length documentary about the story, the movie, which opens Friday in San Francisco and Berkeley, examines the historical context in which the SLA was founded and how the group managed, in surreal fashion, to capture so much of the nation's attention -- despite being a small ragtag band of self-styled revolutionaries who may have defended their actions with high ideals but were deeply misguided, John McMurtrie profiles the film and speaks with director Robert Stone in the San Francisco Chronicle.
