It wasn’t terribly surprising when Disney revealed they were planning The Jungle Book 2, with the sequel in development just days before The Jungle Book hit theaters.
The first Jungle Book movie didn’t explore every aspect of the Rudyard Kipling story, which was expanded with the author’s sequel book as well, so there is plenty more material to adapt for The Jungle Book 2 and other subsequent sequels.
It seems likely that the December 20, 2019 date would be the one used for The Jungle Book 2, although it remains unclear when filming may begin.
The Jungle Book would go on to be one of the biggest box office hit in 2016, bringing in $364 million domestic and $966.5 million worldwide, from a $180 million budget.
