'The Devil Next Door;, a documentary series on Netflix about the 1980s trial of John Demjanjuk, the Ukrainian-American accused of being 'Ivan the Terrible', a hideously cruel guard at Treblinka death camp during the war. In film of the trial, he appears to be burly, genial, not very-bright retired factory worker in his 60s. I've got one episode to go, but he was eventually acquitted of being I the T when evidence was produced that Ivan was killed during a prisoner uprising, but he was a guard.
