The sadest thing I have ever saw was the little girl in Schindlers List. She is the one in the little red coat in a sea of black and white images. You know she is walking off to die and it wrenches my heart everytime I see it. That has got to be one of the sadest movies I have ever saw. Now for the sadest line? Maybe when Schindler says " I could of sold my jewerly and saved 3 more, maybe the car,6 more, I could of done more!
