The two "Mouse" films benefitted greatly from the wonderfully funny source novels by terribly under-appreciated Irish author Leonard Wibberley. Although the second film suffers in comparison because of the loss of star Peter Sellers, the performances by Ron Moody as Count Mountjoy and Dame Margaret Rutherford are still quite effective. It must be pointed out that some of the higher bits of satire of Wibberley's novel have gone missing from the film. In the novel, the Duchess (a 23-year-old married to Chief Forester Tully Bascomb) asks Count Mountjoy (she has called him "Bobo" since infancy) for an Imperial Russian sable fur coat. Mountjoy, desiring to update the Grand Fenwick castle's 14th century plumbing, gets a decree passed asking for a loan from the United States for $50,000 for the coat. Being the sly fox that he is, he also asks for $5 million to enter the SPACE PROGRAM! Of course, Mountjoy has every intension of buying the Duchess her coat and using the rest on the plumbing (and also for road improvements, as there are no paved roads in the country). The USA realizes that it's a ruse of some sort, but sees it as an excellent PR opportunity and decides to give them $50 million instead! The rest of the plot is pretty much directly translated into the film. Too bad Wibberley's remaining books in the series ("The Mouse on Wall Street," "The Mouse That Saved the West," and "Beware the Mouse!") were never filmed.
