Audio problem: Apparently, Ralph's surname was changed at the last minute from the British Royal Family surname of "Windsor" to "Windham." There are several points in the film, where there is a lip-sync problem, due to the differences of the name, because it has been dubbed.

Continuity: The scene is where Duncan is sitting across from Ralph trying to convince him that he's the king. It's a taco stand or something. At the start of the scene you see a bottle of Tabasco sauce on the table. In the next view, the bottle is gone and Ralph gets up to get a bottle of Tabasco sauce from the counter.

Factual error: There are numerous references made to the Finnish Royal Family, and they even make an appearance. Only problem is, Finland doesn't have a Royal Family.
