Other mistake: After Phillipe escapes from the dungeons of Aquila, the head of the guards demands 10 men to go with him, to recapture Phillipe. But as they leave, we can see only 6 men accompany him.
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.
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)
