Same as a few people here... for some reason "donkegin" just came to mind so I googled it, could recall the name of the movie but totally loved it, still do: it's also a great way to show kids how myths, legends and their names are created and specially love the way it involves Dream Time and Kadaitcha man... this is one of many 70' and 80's Aussie movies that need to be in the cinemas now and possibly remade.
