Wild Innocence (1936)

A film, based on a Cosmopolitan Magazine story by Dorothy Cotterell, is basically a story dealing with civilization's effect and man's cruelty on the Australian outback. It begins with footage of wild animals in their own habitat, and then cuts to episodes of circus life, with Chute, the boxing kangaroo being mistreated by its trainer. Chute's original owner comes to his rescue.
