Disney showed off a lot of new movies at its D23 conference last month, but one of the most arresting pieces of footage was from The Jungle Book — and now it's time for the world at large to see the first trailer. Jon Favreau is directing the adaptation of Disney's animated film, and while it's part of the studio's larger initiative of turning its classics into live-action films, the new Jungle Book is actually a CG and live-action hybrid. The animals and environment are actually photorealistic computer-generate imagery, merged together with performance capture and footage shot of the cast, particularly Neel Sethi, who plays Mowgli.

The film also stars such heavyweights as Ben Kingsley, Idris Elba, Scarlett Johansson, and Christopher Walken, but the performance that got the biggest reaction during D23 was Bill Murray as the bear Baloo. The original Jungle Book was a musical, with a duet between Mowgli and Baloo called "The Bare Necessities" serving as one of the most memorable numbers from the film. In the D23 footage, Baloo was shown floating down a river, subtly humming "Bear Necessities" to himself, serving as a bridge between the classic film and the modern update. The Jungle Book is set to open on April 15th, 2016.
