The film that put the Duchy of Grand Fenwick on the map, and sold Americans on that fine British import, Peter Sellers. He cavorts through the film in three different guises. As the big-bosomed Grand Duchess Gloriana, he is just Divine. As Mountjoy, the wily Prime Minister of this smallest nation on earth, he devises a scheme to declare war on the U.S. in hopes of reaping the benefits of reparation. And as Tully Bascombe, the bumbling leader of Grand Fenwick's army of archers (20 strong), he gets his hands on the most dangerous and controversial weapon ever invented, the dreaded "Q bomb." So The Mouse That Roared becomes delicious Cold War comedy, based on the then-preposterous proposition that a small nation could acquire the Bomb and hold the planet hostage.... Anyway, it's all very funny, and quite nicely resolves itself in the formation of a special United Nations made up of very tiny countries.
