La Loi C'est la Loi on AllMovie

Fernandel plays a French customs sergeant who conducts an ongoing war of nerves with Italian smuggler Toto on the Franco-Italian border. The French sergeant discovers that, through a long-ago hospital mix-up, he is actually an Italian citizen. Now Fernandel is legally prevented from arresting Toto--and to make matters worse, he is the lawbreaker in Italian eyes because of his divorce and remarriage! The publicity attending the long-anticipated teaming of France's favorite funnyman Fernandel (born Fernand Joseph Desire Contandin) and his Italian counterpart Toto (born Antonio de Curtis Gagliardi Ducas Comneno di Bisanzio) helped to make The Law Is the Law one of the most successful films in both comedians' careers. The film, incidentally, was a French production (originally titled La Loi c'est la Loi), so in fact it was Toto, not Fernandel, who was the "alien."
