Our Man in Havana

In Cuban Revolution Cuba, James Wormold (Alec Guinness), a vacuum cleaner salesman, is recruited by Hawthorne (Noël Coward) of the British Secret Intelligence Service to be their Havana operative. Instead of recruiting his own agents, Wormold invents agents from men he knows only by sight and sketches "plans" for a rocket-launching pad based on vacuum parts to increase his value to the service and to procure more money for himself and his expensive daughter Milly (Jo Morrow).
