Revealing mistake: After the prince is crowned king, Robin and his mates leave the castle. If you look to the upper-right of the screen, atop a hill in the distance, you can see a modern-day metal telegraph tower (cinematic version).
Revealing mistake: Early in the movie, as they are heading down to the beach in France to board the ship to England, a plane contrail is seen in the sky.
Chosen answer: A "mile" is not American in origin. The British adapted it from the ancient Roman term, "mille passuum," meaning one thousand paces or strides. Each pace was the length of five Roman feet, resulting in a mile that was approximately 5,000 feet long. This measurement fluctuated up until the Tudor era, when Parliament established the current measuring standard, though the metric system, which was developed by the French in the late 1700s, has since replaced it in Europe and elsewhere. Britain still uses mile as a standard measure of distance on road signs and for speed limits, etc.
