I think it’s important to first point out that this film is based on a true story. Journalist Charles Horman was one of the victims of the Chilean coup of 1973 led by General Augusto Pinochet, that deposed the socialist president, Salvador Allende. The coup was, in part, secretly backed by the United States government. The book on which this film was based came out in 1978 and this film was released in 1982, but the classified documents that prove that the events depicted in both are true were not released until 1999. I find this whole back story insanely interesting and if you’d like to read more about it, the Wikipedia article on Horman has a lot of information and links to further reading. The film was nominated for four Academy Awards, winning one: Best Adapted Screenplay (won), Best Actress Sissy Spacek, Best Actor Jack Lemmon and Best Picture. Strangely, Costa-Gavras was not nominated for Best Director (Wolfgang Petersen got nominated for Das Boot, while the film was not up for Best Picture). The other nominees for Best Picture that year were E.T.: The Extraterrestrial, Tootsie, The Verdict and winner Gandhi.
