A man moves into a small town in the 1890s. He speaks to no one, communicating by occasional note. It is directed by Jacques Tourneur as 'Jack' Tourneur, one of the last shorts he directed before turning full-time to features.
John Nesbitt's long-running MGM series, THE PASSING PARADE, usually showed audiences reenactments of true events, or educated them about some small point overlooked by many. Many of the events were fictionalized, but I cannot recall seeing another which admits that it was all fiction, although based on 'scientifically proven psychology.'
It is, alas, one of the weakest of this interesting series, based upon the hysteria Nesbitt shows, from the short's title to the people who prepare to lynch Paul Guilefoyle.
