In the movie, Tony competes in the 100-meter backstroke, winning a silver medal at the Empire Games in 1962. In 1962, the Empire Games swimming events were measured in yards, and Tony won silver behind another Australian in the 220-yard event. When he is later told that "your event was today" in reference to the 1964 Olympics, it refers to the 200-meter backstroke - the 100 wasn't contested in Tokyo.
There was a scene where Tony meets his future wife at Harvard. It was a beautiful scene filmed at sunset at University of Queensland, in almost the same location at UQ where Tony runs into raving fans, however it was in the area of the main campus building. There were classic Corvettes and other classic American cars. Unfortunately this scene didn't make it into the movie and hasn't been included in the DVD extras.
