Cinema is an industry. Its income depends on the number of people paying for films, which logically depends on their popularity. Which in turn depends on the extent to which it conforms to the expectations (of a film) of a large number of people. Their mores include things they really care about (sport, money, life and death, nationalism—perhaps in that order) and things they think they should be seen to care about because of political correctness (indigenous issues, feminism, animal welfare).
This year’s top Aussie film has had an exemplary ride. It did very well at the box office, making far more millions than any other in 2019 … until the scandal hit the media. Never having thought about it, people were shocked to discover that horsemeat is being used for pet food. Not only that, people were actually killing the horses first.
The film will still finish first, but now rather ignominiously. I expect there will be demonstrations on AACTA awards night, and that people will say disparaging (or defensive) things about the racing industry in their speeches.
Footnote. What is done to racehorses during their working lives is far worse than what happens to them in the minutes before their deaths.
