This film of Ira Levin's novel The Boys from Brazil wastes no time in establishing the fact that several seemingly unrelated men have been mysteriously murdered. Elderly Jewish Nazi hunter Ezra Lieberman (Laurence Olivier), brought into the case when the clues seem to point to a neo-fascist plot, traces the trail of evidence to Paraguay. Here he finds an unregenerate Auschwitz doctor, patterned on Joseph Mengele and played by -- of all people -- Gregory Peck. Lieberman discovers that the murdered men had all fathered sons who were identical -- the results of a cloning experiment, designed to create a race of incipient Hitlers.~ Hal Erickson, All Movie Guide
