 DATE: In the movie, Pedersens wife leaves for the northern town of  Mo i Rana, while in the novel, she goes to the town of Harstad. The  director has explained that this change was made because she was a  librarian, and that Norways National Library has a branch in Mo i  Rana. However, while the story is set in the 1970s, the National  Library in Mo i Rana was not established until 1989.
