There was an Italian movie--a comedy with serious overtones--called "Mafioso" from 1962, directed by Alberto Lattuada and starting Alberto Sordi. I saw it only once, in '62, and have never been able to find it. I never forgot it because it was one of the greatest films I'd ever seen. The plot revolves around a Sicilian guy who'd emigrated to Milan, where he got a respectable job in the Alfa Romeo factory and worked his way up to manager; married a blond Northern Italian woman; had a couple of kids with her, and was making his first return, with wife and kids, to Sicily in many years. He gets involved with the local Mafia chief, who orders him on a far-fetched hit. The moral of the story was: once a Sicilian, always a Sicilian. Many riotous touches in this film, but it was strong and grim nonetheless.
If that's the film, Joe, JUMP ON IT!! Please post if it is.
