In the 1979 BBC production of "Rebecca", Joana David portrayed the 2nd Mrs. de Winter. She is Emilia Fox's mother.
During WWII, the German Army used the novel "Rebecca" as the key to a book code between Rommel and German Abwehr agents guided by Count Laslo Almasy invading Cairo. However, the code was abandoned when the radio section of HQ was captured in a skirmish, potentially compromising the code.
