Tarzan of the Apes (Michael Wildshill film)

Tarzan of the Apes is a cancelled animated film adaptation of the novel of the same name by Edgar Rice Burroughs that was to be produced by Gingo Feature Animation for Universal Studios.

Plot
The story follows Tarzan's adventures, from his childhood being raised by apes in the jungle, to his eventual encounters with other humans and Western society.

Why It Was Cancelled

 * 1) Disney was already working on a film of their own.
 * 2) Gingo found the screenplay not very faithful to the source material.
 * 3) Many of the Gingo Feature Animation staff went on to work at Universal's animation facility in Universal City.
 * 4) Michael Wildshill was busy working at Universal Animation.

Result
After Gingo cancelled their plans for a film adaptation, Disney released an animated version of their own in 1999 and was a box office hit.
