Please answer the following question: I am a movie director and I just received the following movie plot. Could you help me answer this question? If not, let me know by writing "Not answerable". Plot title: The Mouse That Roared Movie plot: The Mouse that RoaredThe world's smallest nation, the Duchy of Grand Fenwick, which lies on the Swiss-French border, is quietly and prosperously ruled by the Grand Duchess Gloriana XII (Peter Sellers), with the assistance of the Hereditary Prime Minister, Count Rupert of Mountjoy (Peter Sellers), the Hereditary Field Marshall and Grand Constable, Tully Bascombe (Peter Sellers) and the Leader of the Loyal Opposition, David Bentner (Leo McKern).Disaster strikes, however, when the Duchy's only export, its wine, Pinot Grand Fenwick, is undercut in the United States by a Californian copy, Pinot Grand Enwick. Faced with bankruptcy, and having had no reply to its protests, the Duchy decides to declare war on the United States, Mountjoy having reasoned that it will certainly lose and will then be magnificently rehabilitated by the generous, victorious Americans. A Declaration of War is duly sent, but is considered a press-room joke by its recipient in Washington.Tully Bascombe, his lieutenant Will Buckley (William Hartnell), and twenty soldiers, in chain mail and armed with longbows, including Roger (Timothy Bateson) and Cobbley (Monte Landis) and (Alan Gifford), are sent to invade the United States, making the first part of their journey by bus and then by tramp steamer, captained by Pedro (Harold Kasket), encountering, en route, the QEII (captain Stuart Saunders, second officer Ken Stanley), which they mistakenly attack.In New York, an air-raid exercise has closed the entire city, with the exception of the laboratory of Professor Alfred Kokintz (David Kossoff) at the New York Institute of Physics, where he and his daughter Helen (Jean Seberg) are working on the new Q-bomb: an air-raid warden (Wally Brown) tries to get them to take shelter, but the Professor shows him the Q-bomb - an active working model on a hair-trigger - which he must deactivate first. The Grand Fenwick party land, but can find no-one to surrender to: in Central Park, they encounter a decontamination squad, Mulligan (Richard Gatehouse) and O'Hara... My question: Who discovers that Grand Fenwick's bomb is a dud?
Answer:
Professor Kokintz
