When you watch the trailer for Jon Favreau's adaptation of The Jungle Book (it's an adaptation of the cartoon, not the original book) you have to know one thing:
None of this is real.
They shot the whole thing, I believe, on stages. There are no real animals in the movie. Everything you see, except for the kid playing Mowgli, was created in a computer. I think it all looks incredible.
And this is just the tip of the iceberg. The footage we saw at D23 from this film included a bunch of shots of the animals talking, and they looked incredible. There's no phoniness there; the animals still looked like real, living animals but also like they were talking. It wasn't cartoony. I wring my hands about CGI a lot but when used like this - to create photoreal animals that talk and interact with humans - it seems completely right.
I'm not sure if I've ever seen the entire original Jungle Book (I certainly had a book and record combo I listened to as a kid) but I will be first in the theater for this version.
