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?
Factual error: When Simba and Nala meet as adults, they rub heads and begin to purr. Lions can purr, but they only purr when they exhale, and Simba and Nala were purring when inhaling and exhaling, like house cats. (00:58:15)
Factual error: When Mufasa is initially showing Simba the pridelands they are facing the rising sun - in other words east. Simba asks about "that shadowy place" which is off to the right, and is told he must never go there. When Simba is later telling Scar about seeing the whole kingdom, Scar says "He didn't tell you what's beyond that rise on the northern border." It's the same place that Mufasa was talking about, as Simba says he's not allowed to go there, but if it was to the right as they faced east it would have been the southern border of the pridelands.
