The movie is an adaptation of Truman Capote's novel of the same name. The story revolves around two small time ex-cons. Perry Smith (Robert Blake) and Dick Hickock (Scott Wilson) have recently been released from prison. These two individuals don't seem to be very intelligent and if they were by themselves, they probably would have been the same petty criminals they'd always been. Together, they are a deadly duo.

In Cold Blood was filmed in Holcomb, Kansas at the Clutter farm where the actual murders took place as well as the other actual locations. At the trial portion of the film, six of the original jurors were used as actors in the jury box. When Hickock and Smith are hanged, the hangman you see is the same man who performed the real hanging.

Excellent acting performances are turned in by Robert Blake and Scott Wilson in this gripping drama. A must-see movie!!
