References to the Nazi invasion in the movie 'the others'

In the movie the others Nicole Kidman seems to make several references to the Nazis invading and occupying England during WW II, which never happened. What was this about, and was there signifigance to this?

The Others was supposed to take place on one of the Channel Islands (Jersey, I think), which were German occupied for most of WWII.

Ah, my mistake. I thought this movie took place on mainland England.
