The Boys from Brazil is a 1978 film based on the novel of the same name by Ira Levin. It tells the story of a plot by a group of former Nazis led by Dr. Josef Mengele to clone Adolf Hitler and create a Fourth Reich.
Ezra Lieberman, played by Laurence Olivier, is a Holocaust survivor and Nazi hunter who becomes aware of the plot after several seemingly random assassinations of elderly men around the world. The assassins, all young and from different parts of the world, were all followers of Mengele, who had been hiding in South America and planning the cloning project.
Lieberman travels to South America to investigate and discovers that 94 clones of Hitler have been created, each to be raised by a different family to recreate the circumstances of Hitler's childhood and ensure that at least one of them becomes the new Führer. The final clone is to be born in just a few months' time, and the assassinations were carried out to prevent anyone from discovering the plot.
Lieberman teams up with a young American journalist, played by Steve Guttenberg, and they race against time to stop Mengele and his followers before it's too late. In a dramatic climax, they confront Mengele and the last clone, who has been raised in a remote jungle by a fanatical Nazi sympathizer.
The Boys from Brazil is a tense and chilling thriller that explores the horrors of the Holocaust and the dangers of fascism. It was directed by Franklin J. Schaffner and also stars Gregory Peck as Mengele and James Mason as a wealthy ex-Nazi who is funding the cloning project.
