If you were going to create a movie based around a fighting champion from Australia or New Zealand, the storyline might go something like this: The stoic man from the faraway land was so tough, he broke his leg during his fight with a monster of an opponent and won. Then he rematched the same guy, broke his hand, and won for the second time. Then he returned home, where we didn’t hear from him until it was time to fight again.
The only way such a scenario could be more of a Down Under cliche would be if there were kangaroos bouncing around in the background while all this went down.
