Other mistake: Just after Isabeau falls from the abbey tower and turns into Ladyhawke, a soldier emerges onto the roof of the tower and questions Phillipe. An arrow is then fired (by Navarre) into the left-side of the soldier. However, he initially grabs at his right-side. After a couple of seconds he correctly grabs at his left-side, before falling off the tower. (01:00:26)
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.
