This movie begins with a bumbling agent for British counter-intelligence named "Stanley Farquhar" (Lionel Jeffries) coming upon a brilliant plan to spy on the Soviet Union. His plan, essentially, is to put a bugging device into a bulldog named "Disraeli" which the British Prime Minister is about to give as a gift to his Soviet counterpart. To help with this plan Stanley blackmails a veterinarian by the name of "Dr. Francis Trevelyon" (Laurence Harvey) who has a predilection for the wives of his clients. At first, everything is a smashing success but this all changes when the Soviet Prime Minister sends his best spy, "Princess Natasha Romanova" (Dahlia Lavi) to Britian to uncover the source of the leaks. Now rather than reveal any more I will just say that this movie certainly had its ups and downs with the inconsistent comedy being the main concern. Fortunately, the presence of Dahlia Lavi-along with decent acting from Lionel Jeffries and Laurence Harvey--definitely improved what normally should have been a very lackluster film and for that reason I have rated it accordingly. Average.
