The French-filmed Senechal the Magnificent is set during World War II. Fernandel plays a none-too-intelligent travelling entertainer who, through a case of mistaken identity, takes the place of a famed nightclub artiste named Senechal. Fernandel's gift for mimicry makes him a big hit in Paris; however, he spends most of his time looking over his shoulder, hoping the real Senechal never shows up. When the time comes to outwit the occupying Nazi troops, Fernandel's skill at impressions becomes a life-or-death commodity. Senechal le Magnifique was (surprise!) the original French title for this Danny Kaye-like comedy.
