Referring to something in a story that is entirely out of place in the time period the story is set in.


1) Pirates of the Caribbean: They make a reference to Singapore, even though the movie is set in the 1700s and Singapore wasn’t the name of a place until 1819.

2) Titanic: Leonardo DiCaprio’s character refers to fishing in a lake in Wisconsin that was manmade and not created until after five years after the Titanic sank.
