Continuity mistake: During the Golden Arrow Archery Contest at the point where Robin Hood splits his competitor's arrow, notice the competitor's arrow has one striped feather and one white feather when it hits the target, with the arrow's shadow cast at the 5 o'clock position. Then when Robin Hood splits that arrow with his, instead of two striped feathers it now has one striped feather and one white feather, with the shadow is now cast at the 7 o'clock position. (00:57:00)
Factual error: At the archery contest, the range officer commands the archers to send arrows to the target with the command "Fire." This command did not come into use until the introduction of firearms - matchlocks - late in the 14th century. The command should have been "Loose", or the Middle English equivalent.
