In Cold Blood (1967)
In Cold Blood is a 1967 film based on Truman Capote's book of the same name. Richard Brooks prepared the adaptation and directed the film. It stars Robert Blake as Perry Smith, Scott Wilson as Richard "Dick" Hickock, and John Forsythe as Alvin Dewey. The film follows the trail of Smith and Hickock; they break into the home of the Clutter family in Holcomb, Kansas, kill all four members of the family who are present, go on the run, and are found and caught by the police, tried for the murders, and eventually executed. Although the film is in parts faithful to the book, Brooks created a fictional character, "The Reporter" (played by Paul Stewart). The film was nominated for four Academy Awards: Director, Original Score, Cinematography, and Adapted Screenplay.
