This movie has a chauvinist background to it...
I remember seeing a documentary for this movie a while back and one of the film producer's said that when the script was being made it started out with a man flying from Tokyo to America with his son on a business trip and his son disappears. But they decided to make it a woman and her daughter after the loss of the husband because it would seem more realistic for the people on the plane not to believe a woman who they think came on board alone than a man claiming that his son has disappeared. I guess they assume that since women are still to this day known as the "weaker sex" by idiots that it would be easier to believe that a woman goes crazy than a man going insane on an airplane after the stress of losing a loved one. Good job pricks!!
