Fan Casting The Lion King IV

I imagine that this fourth film would feature humans and it would take place after the events of The Lion King II: Simba's Pride and The Lion Guard (if it is canon) and the story would be shakespearean just like the first two Lion King films and it would answer the question that everyone has been asking "What time is Lion King set in?". I was influenced by Once Upon A Forest, Dawn of the Planet of the Apes, Bambi (the half where he is adult and the sequences that involved man), Jungle Emperor Leo: The Movie, and those episodes of Babar (when he was a kid and featured the hunter) when I thought of this idea. The inhabitants of the Pridelands believed that humans are not real (just like with in Happy Feet) and they refer to the humans as watu.
