The Mouse on the Moon (1963)

Financial disaster looms for Grand Fenwick when the current vintage of its only export, wine, starts exploding in would-be consumers’ faces. Prime Minister Mountjoy decides to ask the United States for a loan, ostensibly to fund its entry in the race to the Moon, but actually to save the duchy (and install modern plumbing so he can have a hot bath). The devious politician knows that the Americans will not believe him, but will consider the half million dollars he is asking for to be cheap propaganda supporting their hollow call for international co-operation in space. He is delighted when they send him double the amount as an outright gift. The Soviets, not wishing to be one-upped by their Cold War rivals, deliver an obsolete rocket.

Mountjoy asks resident scientist Professor Kokintz to arrange a small explosion during the “launch” of their lunar rocket to make it look like they have actually spent the money as intended. Meanwhile, Mountjoy’s son Vincent returns after being educated in England. Mountjoy is disappointed to find that Vincent has picked up the British sense of fair play and the ambition to be an astronaut. Professor Kokintz has pleasant news for Vincent: he has discovered that the wine makes excellent rocket fuel. Together, they secretly begin preparing the rocket for flight. Maurice Spender, a bumbling spy sent by the suspicious British, is given a tour of the ship, including the shower heads converted into attitude jets, and reports back to his bosses that it is all a hoax.
