The Mask of Diijon
When Erich von Stroheim was unable to work directing, he took work acting and turned in some very solid performances. This is one of them. In this movie, he portrays a mad magician who is insanely jealous and devises a plot to hypnotize his wife/assistant into killing the man he suspects to be her lover. A classic case of paranoia and backfiring plots, this movie is otherwise uninteresting and the acting other than von Stroheim's is uninspired.
