I imagine that the Americans and Canadians who went to see this Australian movie in theaters in the 70s felt ripped off. For starters, it was retitled "The Day Before Halloween", yet it has NOTHING to do with the John Carpenter movie of 1978. The only similarity it has is with some of the piano music, which sort of sounds like Carpenter's score at times. But even if the movie had been released over here under its original name, viewers would have felt ripped off. For large chunks of the movie, absolutely NOTHING of consequence happens. All that you'll get out of the movie is that the modelling business can be a cold and cutthroat experience, something I think that any viewer would know already. The trivia section for this movie says that the script was written in ten days. It shows.
