Trivia: In 'Cell Block Tango', the scarves represent murder. While the other four murderesses carry only one red scarf, Velma carries two (one for her husband and one for her sister) and Catalina has one white scarf to show that she alone is innocent.
Trivia: Hunyák's story in the cell block tango (translated from Hungarian) is "What am I doing here? They say my famous lover held down my husband while I chopped off his head. But it isn't true, I am innocent. I don't know why Uncle Sam says I did it. I tried to explain it at the police station but they did not understand me."
Trivia: Catherine Zeta Jones specifically requested to have a short haircut for this movie so that the audience see her face and there would be no doubt that she did all the dancing herself.
