Interestingly the title is
The Boys from Brazil (as is the Ira Levin novel its based on)but the action takes place in Paraguay. The film opens with a Jewish American college student Barry Kohler(Steve Guttenberg)in Paraguay. He witnesses a thriving neo-Nazi community complete with a parade of goose-stepping soldiers. Among the vintage nazis hiding out there is none other than Dr. Mengele whom nazi hunters have been chasing for decades. With a rigged up bugging device (probably considered high tech in 1978)he plants at Mengele's residence Barry records them discussing a plot to revive the Third Reich. Before he hears the entire plan he is caught and killed, but not before playing the tape for and mailing photos to famous nazi hunter Ezra Lieberman (Laurence Olivier). Lieberman travels through Europe and the United States following clues until he discovers the terrifying Nazi plan.
If there is a flaw in this movie it is the overacting of Steve Guttenberg. He just much too happy for a Jewish boy who knows he might be caught by the nazis. Gregory Peck makes up for Guttenberg's poor acting skills..you can tell he's having the time of his life with the part of Mengele at the end when he excitedly describes how he took blood and skin from Hitler for his experiment to create "...the right Hitler for the right future...tailor made for the 1980's, 90's, 2000!" Now if only someone would have thought about cloning ELVIS!!
