Factual error: When the bishop is told Navarre is back and the bishop from the balcony claps and orders for Cezar, the portico behind the servant has a sprinkler pipe running from the first column to the opposite wall. Kind of advanced for a medieval castle. (00:33:00)
Factual error: The hawk that Isabeau turns into is a red-tailed hawk. Red-Tailed hawks are a North American Species and wouldn't be found in Europe.
Suggested correction: There is nothing in the film to suggest that because they live in Europe, Isabeau should only turn into a hawk native to that continent. It's a magical curse. A film can make its own rules how magic works in their universe and in this film Isabeau is cursed to turn into a North-American hawk for whatever reason.
