Amazon.com video review:
Truman Capote's extraordinary nonfiction book about the course
of two killers in this world--their lives, their senseless slaughter
of an entire family, their executions--was faithfully adapted for the
screen in this 1967 film by Richard Brooks (Deadline USA, The Blackboard
Jungle). Robert Blake and Scott Wilson are remarkable as the
murderers, but what has kept this film special over the decades is
Brooks's blunt, clearheaded, and nonsensational approach to the
story. (The term "semidocumentary" has been applied to Brooks's style
on this film, and it's an entirely fair description.) The experience
of watching In Cold Blood is naturally unsettling, but the
director--as with Capote--leaves final judgments about justice to the
beholder. --Tom Keogh
