Disney has released a teaser of its upcoming live-action and CGI film - The Jungle Book - ahead of the film's first full-fledged trailer which releases today (Monday 14 September). The short clip, posted on Disney's Instagram page, shows a stunning jungle landscape with Mowgli standing on a mangled tree branch, covered in vines.

Rustling or perhaps hissing, is also heard, reports E!Online. The much-awaited film is sure to bring back fond memories of the 1967 Disney animated classic and present beloved characters like Bagheera, Baloo the bear and Shere Khan in an updated CGI form.

"It is going to be a very different experience in that it's much more visceral," actor Ben Kingsley (Bagheera) told E! News in August at Disney's D23 convention. "You feel the threat of the jungle, as well as the beauty of the jungle. You feel the power of those beasts as well as the story that they have to tell. You feel that there is something very muscular and vivid about those animals."

"When the elephants came onto the screen, the audience gasped because they do look like a herd of elephants," he said. "You cannot imagine that that was created in a laboratory. It's almost impossible to believe that you're watching computer-generated images."

Newcomer Neel Sethi is playing the character, a boy raised by wolves who communicates with animals. Several actors are portraying CGI-animated characters, including Scarlett Johansson (Kaa, a python), Idris Elba (Shere Khan, an evil tiger), Bill Murray (Mowgli's friend Baloo, a bear), Kingsley (Bagheera, a panther), Lupita Nyong'o (Raksha, a wolf and Mowgli's adoptive mother) and Christopher Walken (King Louie, an Orangutan).

Jon Favreau (Iron Man) is directing the film, which is set for release on 15 April 2016. You can click here to watch the teaser.
