When Paige offers Kirsten to take her place to dance with Edvardm the woman in the back with the red hair appears again when Eddy and Kirsten are dancing and she spins off then trips. She is seen again in the background when Paige brings Kirsten her shawl to cover up after she had ripped her dress. When Kirsten storms off she is behind Kirsten again, then in the background again when Paige and Eddy dance.
Lutheranism is the official religion of Denmark's royal family. The royal wedding was held in a Catholic church with a Catholic bishop presiding.
Throughout the movie, Paige is referred to as "Crown Queen", but this is incorrect. She has no title yet, and would then be referred to as "Miss Paige Morgan". There is no such thing as "Crown Queen", and only after marrying the Crown Prince would she be called Queen.
At a dinner Paige says this Danish sentence "Dronningen er en luder". This is translated in the movie to mean, "The queen is a green donkey," but what it really means is "The queen is a whore." Euphemistic translation was used to preserve the movie's PG rating, besides "green donkey" is simply funnier.
The "loop hole" in the law states that the commoner has to have knowledge about the Danish constitution. This law is from 1282. However the law Paige is reading is from 1953. The earliest constitution is from 1849. However this can be a confusion with the Code of Jutland which is, as stated in the beginning of the movie, from 1241 (but never considered the Constitution of Denmark).
While showing us "Danish" castles and buildings, the movie's opening sequence included a shot of a castle flying Czech flags (blue, red, & white). Like the first movie, parts of the sequel were shot in the Czech Republic.
Denmark has a flat topography. The mountains of Czechia are featured in shots throughout the film.
The license plates on cars are Czech, not Danish.
In The Prince and Me (2004), King Haarald is sick and dying, and that is why Edvard leaves Wisconsin to return home and become king. In this movie, Haarald appears to be alive and well. Also while walking through the garden with the busts of former kings, on looks a lot like James Fox, who played the character in the first movie.
The priest during the wedding said that the Danish crown had been held for 5,000 years. In fact, the Danish monarchy is only about 1,000 years old.
When Paige at a press conference admits that the Danish language is her biggest challenge, king Edvard says - in Danish with a heavy British accent: "Du bli'r hurtigt flydende!" (= you'll get fluid quickly!) He meant 'fluent'. In Danish he might have said: "Du vil hurtigt komme til at tale sproget flydende."
In Danish tradition, wedding bands are worn on the right hand. In the wedding scene, Edvard places Paige's ring on her left hand, as is common in America.
When Paige is leaving a message for her Mom before going to bed she surmises that her Mom is getting ready to start her day. It would have been afternoon in Wisconsin, seven hours behind Denmark.
