"Missing," originally released in 1982 and based on the book "The Execution Of Charles Horman", concerns an American journalist, Charles Horman (played by John Shea in the film), who disappeared in the 1973 coup d'état led by General Augusto Pinochet in Chile. Horman's father, played by Jack Lemmon, and wife, played by Sissy Spacek, search in vain to determine his fate. Nathaniel Davis, US ambassador to Chile from 1971–1973, a version of whose character had been portrayed in the movie (under a different name), filed a US$150 million libel suit, "Davis v. Costa-Gavras", 619 F. Supp. 1372 (1985), against the studio and the director, which was eventually dismissed. The film won an Oscar for Best Screenplay Adaptation and the Palme d'Or at the Cannes Film Festival.
