Kind Hearts and Coronets (1949)

Oh, this sounds promising: A British black comedy in which a betrayed and cast-out Duke vows to avenge himself upon the aristocratic family that wronged him and claim the title . . . by killing every damn one of them. And even better? Every damn one of the D'Ascoyne clan is played by Alec Guinness. So like The Nutty Professor or Austin Powers 3 except British, and therefore funnier and more dignified. Kind Hearts and Coronets made the Time Top 100, and the BFI Top British films list. Should be funnier than The Woman in the Dunes at the very least!
