Pictured above: Storyboard concepts for The Jungle Book's lost character, Rocky the Rhino. Developed by Walt Disney himself, and considered a key character in The Jungle Book, Rocky never made it to the silver screen.

Cinematical was lucky enough to get a hold of these exclusive, unreleased images (with regards to Rocky the Rhino) from the classic Disney animated film, all of which will be featured on The Jungle Book: Platinum Edition DVD, due out in stores on October 2. For a limited time only, fans will be able to help celebrate The Jungle Book's 40th anniversary by picking up the two-disc Platinum Edition DVD of the last animated film to be personally touched by Walt Disney himself.

Apart from these images of the lost Jungle Book character, there's a ton of special features as well, including: "The Bare Necessities: The Making of The Jungle Book" featurette (which includes Walt's contributions to the film), "Disney's Kipling," which examines Walt's interpretation of Rudyard Kipling's "Mowgli Stories," and commentary from the original animators Frank Thomas, Ollie Johnston and director Woolie Reitherman -- alongside additional commentary from folks like Brad Bird (The Incredibles), Glen Keane (The Little Mermaid) and Andreas Deja (The Lion King).

Personally, The Jungle Book was always one of my favorite animated films growing up (I watched it so much at one point that my mother took it away, saying the tape broke, only to find it magically reappear once she was no longer sick of hearing the thing play in the background all day long). We've included a full list of special features (along with their descriptions) after the jump, as well as an exclusive image gallery to check out below. The Jungle Book: Platinum Edition DVD arrives on shelves this October 2.
