Continuity mistake: At the big fight between the peasants and Einon's knights, Bowen strikes one enemy from behind with his sword. Not only does it look like he strikes between upper torso and right arm, but also when he retrieves his sword, there is no blood stain on it.

Factual error: When Draco is first "shot" to hustle money from the villagers, we see an overhead shot of him swimming underwater. However given the amount of water he's deplacing while swimming, we do not see any swell or disturbance due to water refraction of him beneath the surface that would clearly have been visible.
