Serkis added that Mowgli would be an "emotional version" of the literary classic.
Netflix has now unleashed a new trailer to go along with their announcement of the film's pre-streaming theatrical release, and it's safe to say that this menacing and dark take on the Jungle Book tale might not be suitable for the youngest of audiences.
The film will be released in Los Angeles, New York, San Francisco, and London. Viewers not keen on heading out into the chilly autumn air to catch the fantasy adventure flick can stay indoors and load up Mowgli on Netflix starting on December 7.
Blending live action and performance capture, the story follows the upbringing of the human child Mowgli raised by a wolf pack in the jungles of India. Mowgli will certainly need Baloo and Bagheera's help when he is confronted with dangers lurking in the jungle and, even more nerve-wracking, his human origins.
As well as directing, Serkis voices the role of Baloo the bear in the CGI live action film.
But while filming began in March 2015, after which an intense period of post-production was underway, Disney released its own grounded and somewhat gritty The Jungle Book in 2016. Legend of the Jungle stars young newcomer Rohan Chand as Mowgli, with a big ensemble cast including Christian Bale, Cate Blanchett, Benedict Cumberbatch, Naomie Harris, Andy Serkis, Matthew Rhys, Freida Pinto, Peter Mullan, Jack Reynor, Eddie Marsan, and Tom Hollander.
