A quirky British Secret Service Agent discovers a link between the loss of experimental planes and an espionage ring
This comedy spy thriller began with the working title Foreign Sabotage and was released in the US under the name Clouds Over Europe. To depict a journey to Cornwall (!) the film features one brief, but pretty decent glimpse of an LMS passenger service hauled by a 3P Class 4-4-0.
