Rudyard Kipling's iconic tale The Jungle Book has been told on the big screen numerous times in the past, including Disney's iconic animated adaptation that hit theaters in 1967. Nearly 50 years after that beloved movie, fans will get to experience this adventure in a whole new way with director Jon Favreau's The Jungle Book, starring Neel Sethi as Mowgli, the movie's only live-action character, with a host of talented actors voicing the numerous animals this youngster meets along the way. As we get closer to the April 15 release, Moviefone has debuted an extended IMAX trailer, with an introduction by Lupita Nyong'o (the voice of Raksha), which sheds some new light on how Mowgli ended up in the jungle in the first place.

This clip features Mowgli's introduction to the the powerful snake Kaa (Scarlett Johansson), who shows this young "man-cub" just how he was left alone in the jungle. We saw in an earlier clip that the villainous Shere Khan (Idris Elba) wanted Mowgli out of the jungle, but as it turns out, he was actually somewhat responsible for this youngster being raised there. This scene shows a traveler taking shelter in a jungle cave, where a fire is burning, when Shere Khan attacks and kills this man, leaving Mowgli to fend for himself, before he is found by Bagheera (Ben Kingsley).

Directed by Jon Favreau, based on Rudyard Kipling's timeless stories and inspired by Disney's classic animated film, The Jungle Book is an all-new live-action epic adventure about Mowgli (newcomer Neel Sethi), a man-cub who's been raised by a family of wolves. But Mowgli finds he is no longer welcome in the jungle when fearsome tiger Shere Khan (voice of Idris Elba), who bears the scars of Man, promises to eliminate what he sees as a threat.

Urged to abandon the only home he's ever known, Mowgli embarks on a captivating journey of self-discovery, guided by panther-turned-stern mentor Bagheera (voice of Ben Kingsley), and the free-spirited bear Baloo (voice of Bill Murray). Along the way, Mowgli encounters jungle creatures who don't exactly have his best interests at heart, including Kaa (voice of Scarlett Johansson), a python whose seductive voice and gaze hypnotizes the man-cub, and the smooth-talking King Louie (voice of Christopher Walken), who tries to coerce Mowgli into giving up the secret to the elusive and deadly red flower: fire.

The all-star cast also includes Lupita Nyong'o as the voice of the fiercely protective mother wolf Raksha, and Giancarlo Esposito as the voice of wolf pack's alpha male Akela. The Jungle Book seamlessly blends live-action with photorealistic CGI animals and environments, using up-to-the-minute technology and storytelling techniques to immerse audiences in an enchanting and lush world. The wild adventure swings into theaters in 3D on April 15, 2016. The Jungle Book will debut in a rather competitive weekend, going up against Barbershop: The Next Cut, Everybody Wants Some and Criminal. Take a look at the all-new extended IMAX trailer from The Jungle Book, before it hits theaters in just a few weeks.
