Tarzan of the Apes

Tarzan of the Apes is a 1999 animated musical adventure film produced by Diane Eskenazi and Darcy Wright and written by Mark Young. Richard Wagner's Ride of the Valkyries was used as the score during the opening scenes of the film. It was released directly to home video on March 9, 1999. The apes appear to be chimpanzees in this version, however they are not explicitly identified as such, unlike the unrelated 1999 Disney film in which they are gorillas.
