None of the contestants were ever informed what event they would be doing that day, or where they would be taken.
One of the show's directors is Korean and could not understand a word of Mandarin.
All money and identification were taken away from the male contestants the first day in Queensland. One of the show's directors felt sorry for the smokers and bought them one carton of cigarettes each to last the entire production.
Each contestant was given 3 t-shirts of their color, and was required to wear them at all times during shooting.
All crew members and the hosts wore the same t-shirts as the contestants, but in blue.
