A Stranger Came by Train

Overview:

An American gangster of Swedish origins returns to his homeland to set up shop as a morality crusader, much in the manner of the later phenomenon of televangelists. While indulging in behind-the-scene shenanigans including rape and murder, the gangster (played by American Clu Gulagher) preaches to large audiences, using mass hypnotism and show-biz razzmatazz to get his message across. The film also features a brief performance by Per Oscarsson, following his highly publicized "retirement" from screen acting.
