Factual error: When Mufasa is showing Simba the kingdom from Pride Rock they are facing the sun, yet Pride Rock's shadow is visible below them. Also in the same position, you see that they have shadows behind them. Then a few seconds later when Simba sees the shadow area the shadows are in front of them while you can see part of the sun to their left side. They would be facing south when the sun is east. How are their shadows in front of them?
