Howling III: The Marsupials

Professor Harry Beckmeyer (Barry Otto) is convinced that werewolves exist -- a belief stemming from video footage shot
in 1905 by his grandfather in Australia. In the footage, a group of aborigines stand in front of what appears to be a werewolf that
they have tied to a tree and killed with their spears.
When Beckmeyer hears reports of werewolf sightings in Australia, his longtime dream starts to become a reality.
