Robert Blake, billed early in his career as Mickey Gubitosi and Bobby Blake, was an American actor. He was best known for starring in the 1967 film In Cold Blood, playing the title role in the late 1970s television series Baretta, and playing the Mystery Man in the 1997 film Lost Highway.

In Cold Blood is a 1967 American neo-noir crime film written, produced and directed by Richard Brooks, based on Truman Capote's 1966 nonfiction novel of the same name. It stars Robert Blake as Perry Smith and Scott Wilson as Richard "Dick" Hickock, two men who murder a family of four in Holcomb, Kansas. Although the film is in parts faithful to the book, Brooks made some slight alterations, including the inclusion of a fictional character, "The Reporter". The film was shot on location at sites where Smith and Hickock's crimes occurred, including the real Clutter home where they robbed and murdered all four members of the family. The film was nominated for four Academy Awards: Best Director, Best Original Score, Best Cinematography, and Best Adapted Screenplay. In 2008, In Cold Blood was selected for preservation in the United States National Film Registry by the Library of Congress as being "culturally, historically, or aesthetically significant".
