Another Friday in May means another sampling of Orson Welles films. One of them, at 10 p.m. ET, is Welles’ 1963 version of The Trial, a moody story that is more than Kafkaesque. It is Kafka, based on one of his novels. But the first movie in this Friday night doubleheader is 1946’s The Stranger, in which Welles not only directs, but stars, as a suspected Nazi war criminal hiding in plain sight on an American college campus. Edward G. Robinson and Loretta Young co-star, and this film, released only a year after the end of WWII, includes what may well be the earliest footage of Nazi concentration-camp footage incorporated into a Hollywood movie drama.
