An impoverished backward nation declares a war on the United States of America, hoping to lose, but things don't go according to plan. Starring Peter Sellers (best known for his roles in MURDER BY DEATH and DR STRANGELOVE) in the three title roles of Tully Bascombe, the Grand Duchess Gloriana XII and Prime Minister Count Mountjoy. THE MOUSE THAT ROARED is the hilariously funny story of the impoverished nation of Grand Fenwick, who, hoping to lose so that they can collect lots of American post-war aid, declare war on the United States. A classic satire starring one of the world's favourite comedians at his very best, THE MOUSE THAT ROARED is the film that united the nations in roars of laughter.
