Watch the First Trailer for Disney's New 'Jungle Book'

This isn't your parents Jungle Book.

This new interpretation of Disney's 1967 animated classic looks much more ferocious than anything we're used to seeing in children's films.

With Scarlett Johannson, Bill Murray, Idris Elba, Ben Kinglsey, Lupita Nyong'o and Christopher Walken lending their voices, it's a star-studded cast that you won't be able to see.

In fact, the only live-action element in the entire movie is Mowgli, played by Neel Sethi.

The film opens in April 2016 and there is already a second one in the works, Jungle Book: Origins, slated for 2017.
